Introduction:
Welcome to Def Jam Rapstar, created by Def Jam and 4MM. Let's get this out of the way right off the bat. No, this is NOT a fighting game like the past few Def Jam titles we have seen. It is a singing game much like Lips, but aims to fill a niche for those of us who enjoy rap music. The game covers music from the early days of rap through the present, and I feel it provides a pretty good mix of old school classics and modern day hits. It also claims to be the first game with vocal recognition, and therefore humming through the songs will not work in this game. You'll fill your meter and keep a multiplier up if you do this, but will be graded poorly on "Lyrics" and therefore it is strongly advised that you actually Rap/Sing all of the parts. Anyway, on to the walkthrough!

Step 1 - Career:
You can access career through the Main Menu. You'll choose "Play" and then "Career". Career consists of five "stages", each requiring you to earn a certain number of "Mics" on the collection of songs provided in order to move onto the next stage. Each stage also provides four challenges. One is always a "New Song" challenge, and will unlock a new song within that stage for you to earn more mics on. The other three are some combination of Endurance, Timing, Multiplier, High Score, or "Platinum Power" (Basically like star power in Guitar Hero, except it automatically activates once you fill it).

Work your way through career, and understand that no specific difficulty is required for any of the career-based achievements. Personally I started on Hard in order to get the "Unstoppable" achievement at the same time, but the bottom line is that you never have to select anything other than easy for career. You do, however, want to ensure that you are getting every possible mic available for all individual songs and ALL challenges. EVERY mic is needed in order to get the "Mic Fiend" achievement (305 Mics in Career). When career is finished with all mics, you should have a bare minimum of 20 achievements worth 475.

As an added note, if you have the Vision Camera or Kinect, you should hook it up and also be trying to get those achievements out of the way at the same time. For these, you want to make sure that you save 15 of your performances total, upload ten of them to the Community, making sure that at least one of them is a "5 Mic" performance and that you add a "Visual Effect" to one also. These steps will earn you an additional 5 achievements for 75. That wraps up everything for career.

Step 2 - Mop Up Remaining Offline Achievements:
Now you have reached the point where difficulty matters for some achievements and not others.

Expert: For expert difficulty, you only need to do two things. First play a song on expert with no help from vocals (On the difficulty select screen, choose "No" under "Vocals") and earn 3 mics (On Point). It is the most difficult achievement in the game, so follow the guide for help on that. Next, you can turn vocal help on again, and be sure to get 5 mics to earn the "DEF JAM SEAL" achievement. If you can get 5 mics with no vocal help at the same time, it will save you one song's worth of time. This is an additional 2 achievements for 50.

Hard: First of all, you will need to play a minimum of 50 songs on Hard, which is why I mentioned that during career, I started on Hard to get some of these out of the way. You need to get at least 3 mics on 50 songs. Next you will want to pick a song that has a singing part. On this song you need to get above 90% on all three graded categories at the end. Finally, plug in a second mic and choose a song you know well. Simply get five mics by singing the whole song into both mics, and you'll be done Hard difficulty. Everything remaining can be done on Easy. This is another 3 achievements for 100.

Easy: This is where the rest of the mopping up will be done. First, create a playlist of ten songs you KNOW you 5 mic. Getting 5 mics on all of them will earn you 3 total achievements for 35. Use an audio effect during any of the songs for another 5. Next, go into freestyle mode and save 5 performances. They can each be as short as you want. Saving 5 of those will earn you 2 more achievements for 20. Next you will want to play 30 total duet or battle performances combined. While doing this, ensure that you do a 5-song battle playlist and win every song. Also, be sure to win both a duet and a battle by 50,000 points each. Then load up a battle and rap into both mics the entire song, making sure to get a 25 rap-note streak (and because you're rapping into both mics, the streak will count for both players). Finally, load up a battle and follow the method in the guide for winning by 1000 points or less.

Once you get to 30 battles and duets combined, and have done all of the other things I just mentioned, you will have earned another 6 achievements for 80. You should also be around 140 - 160 songs total if career took you as many attempts as it did myself. You'll then want to play a few songs you know very well. Get Platinum Power 4 times in a song, and get "Dope" for all lyric sections in a song, and by now you should have gotten 10,000,000 total points across all modes for sure. That's 3 more achievements for 100. The only remaining achievement to mop up is 300 total songs. Follow the guide for the quickest method. This earns you the last 20 to get from playing songs. You should now have 46 total achievements for 960.

Step 3 - Go Into Community and Mop Up the Last 4 Achievements:
Follow the guide for the final 4 achievements, which are received for watching 50 videos, rating 1 video, having a video watched 2000 times, and having a 4-star rating on a video after it gets 200 ratings. This earns your last 40 and will finish up the game. Congrats!

Conclusion:
A very fun rhythm game, especially for fans of rap, and also a pretty easy 1000 points for those who give it a shot. It may not be the best game ever made, but I think it is incredibly fun and also introduces some new technology that fans of Rock Band and Guitar Hero have been waiting for: Vocal Recognition.

Mic Check One Two, One Two

5
Use an audio effect on any song in any game mode

As you progress through the career, you will unlock different visual effects for use in the game. During any song, hit start, and select "Settings". Go down to "Audio Effects" and assign an effect to a button. Return to the song, and press that button to use the effect. This achievement will pop at the end of the song.

See achievement description for "Ain't Scared to Share It".
You Be the Judge

10
Rate a video on the Community

From the main menu, choose "Community" and then scroll down to any of the three options below. Any option will do. Choose any video with , and then press to bring up the "Rate" option. Give it however many stars you would like, and press to confirm. The achievement will pop immediately.
Cultivating Music

5
Unlock a song for the first time

Each stage has one challenge that is a "New Song" Challenge. Choose any of those songs (Fight The Power in Stage 1, Big Poppa in Stage 2, Lean Back in Stage 3, It Takes Two in Stage 4, or Put Your Hands Where My Eyes Can See in Stage 5) and hit the target score for it, which WILL adjust based on what difficulty you choose Easy difficulty will lower the points needed, as you can collect a much fewer number of points to begin with.
Scorch The Booth

10
Save your first Freestyle performance

See the achievement description for "Lyrical Player Pro".
Fresh Out The Box

10
Complete your first Challenge in Career mode

The first challenge you will have access to is on Stage 1, and is Public Enemy's "Fight The Power". Achieve the target score for the song, which adjusts based on the difficulty you choose (less points are required on Easy because you cannot earn as many points). You will earn the song to play in normal career for a chance to earn 5 mics on it, as well as earn this achievement. It will unlock as soon as you get to the results screen. You will also unlock the achievement "Cultivating Music" at the same time if done this way.
Flawless Flow

10
Earn 5 microphones on any song in Career mode

This achievement can be obtained on any difficulty, and requires 5 mics, or "Off The Chain" rating on any song. You will need to repeat this about 40+ times if going for "Microphone Fiend!", so this will come very early on the way to that achievement. If all else fails, choose the song you know best and put it on Easy Difficulty.
Seal the Deal

40
Earn the DEF JAM RAPSTAR Seal on a song
(4)
Similar to "All Eyez On Me" achievement, except you do not have to turn the vocals off. So pop it on Expert difficulty, and choose "Yes" for vocals. This makes things much easier, as you still have the rapper singing to sing along to at least. The best recommendation I can make is to choose the song you know absolute best. Aside from that, practice and be sure to hit 5 mics. The achievement pops at the results screen.

NOTE: You can obtain both this achievement and "All Eyez On Me" in one attempt if you can manage to hit 5-mics on Expert with Vocals set to "No". Follow the guide for that achievement if you wish to attempt it that way.
Worth Some Millions

40
Accumulate 10,000,000 total points across all game modes

10 Million points is not a lot at all in this game, so this will not take nearly as long as it seems. A typical song on Hard, played well, earns about 300 - 400K per play. Therefore this should come somewhere in the 50 songs needed for the "Unstoppable" achievement. If career is being played on Hard or Medium, it may even come during the career. The achievement pops at the results screen for the song that put you above the 10 million.
It Takes Two

20
Perform 30 Battle or Duet performances in Party mode

By the time all other dual-mic achievements are done, you should be at 7 to 10 Battle or Duet Performances total. Create a setlist of "We Fly High" repeatedly, as it is the shortest song in the game. You can make the setlist equal to the number of performances needed, and you can check that number by going into "Extras" and "Player Stats" from the main menu. Because there is no fail, you can simply press twice to start the next song each time, and walk away and do something else for a couple minutes. The achievement will pop at the results screen for dual-mic song number 30.
Microphone Fiend!

70
Accumulate 305 microphones in Career mode

One of the top three hardest achievements in the game. What makes it bearable is that it can be done entirely on easy. You will need to complete every challenge as well as every individual song at the maximum amount of mics possible. For a couple small tips, see the "RAPSTAR" achievement description. Aside from that, practice makes perfect, and you will have to attempt some songs more than once. The achievement will pop upon 5 Mic'ing the final song or challenge, at the summary screen for the song.
Well Connected

10
Watch 50 videos on the Community
(1)
From the main menu, choose "Community" and then scroll down to any of the 3 categories below. Any option will do. Choose any video with . You get credit for a single view at that point, whether you let the video load or not. So simply keep pressing to bring the video up and then to back out 50 times in a row, as it does not even have to be 50 different videos. The achievement pops immediately after bringing the video up for the 50th time.
Hype'd Up

10
Save 15 recordings to My Videos

Can be done during a career song or any type of party play, so long as a camera is plugged in. At the end of the song, click A to bring up your options. Choose "Edit Video" and then choose the 30-second segment you would like to include. Press when you've done that, and then simply drop down to "Save & Exit", as no effects or changes are needed for this achievement. Do this again with 14 more songs, and the achievement will pop upon saving the last one.

NOTE: Be sure to add visual FX to one of these videos by choosing "Video FX" before you "Save & Exit". Add an effect, back out, then choose "Save & Exit", and you will earn the "It's Like Showbiz" achievement here.
Lyrical Player Pro

10
Save 5 Freestyle videos

Be sure to have a camera connected. From the Main Menu, choose "Play" and then "Freestyle". Select any track, and press to launch it. The track can be as short as you would like. Press to stop the session at any point, and then choose "Edit Video". Press twice to select the section of the video to keep, and then choose "Save & Exit". Give the video a name, and save. Repeat 4 times for a total of 5, and the achievement will pop when the final one is saved.

NOTE: You will unlock "Scorch The Booth" after the very first one finishes saving.
Go The Distance

10
Finish a playlist containing 10 or more songs

From the Main Menu, choose "Play" and then "Party". Now go into ten songs by clicking while on them, and choose "Add To Playlist". Be sure to add 10 songs total. They can even be the same song 10 times, as long as it is ten total. Start the playlist by pressing on the "Song Select" screen, and then button while looking at the playlist. Complete the playlist and the achievement will pop up at the results screen for the final song.

NOTE: The achievement "Get The Party Started Right" will pop as soon as you launch the playlist by pressing . If you can manage to 5-mic every song, you will also get the "Chain Reaction" achievement. If not, load up a new 5-song playlist, ensuring you know how to 5-mic all of the included songs. Remember, it can be 5 or 10 of the same song, just be sure you can 5-mic it.
Livin' Your Life

20
Play 300 performances across all game modes

The best thing to do for this one is wait until you have all 49 of the other achievements. From the main menu go to "Extras" and "Player Stats" and add up the total of Solo, Battle, and Duet Performances. You need 300. Now go to party mode, and create a playlist of "We Fly High" repeatedly. The game has no fail built-in, so you can start the next song in the list and walk away for a couple of minutes. Anyone who has a turbo controller CAN set the button to repeatedly press A and it will start the next one for them, as is the only button needed to be pressed (twice between each song). When the setlist ends, your achievement will pop.
Ain't Scared to Share It

20
Upload 10 videos to the Community

This can be done during a career song or any type of party play, so long as a camera is plugged in. At the end of the song, click to bring up your options. Choose "Edit Video" and then choose the 30-second segment you would like to include. Press when you've done that, and then simply drop down to "Save & Exit", as no effects or changes are needed for this achievement. When you are done saving, a box will pop up asking if you would like to upload the video. Choose "Yes". Repeat these steps 9 more times, for a total of 10 videos, and the achievement will pop as soon as the 10th video has completed uploading.

NOTE: When uploading the 10 videos, be sure to upload one that is a 5-mic performance for the "Immaculately Polished" achievement. You will also unlock the "World Premiere" achievement after uploading your first of the ten.
Unstoppable

50
Get at least "On Point" on 50 performances on HARD difficulty
(3)
Truth be told, Hard is not all that more difficult than Easy. It just take a slight bit more accuracy in order to fill the meter to keep a multiplier up, and that is the only difference. For this achievement, you need to get 3-mics or better on 50 songs on Hard. If all else fails, play some tier 1 songs, and practice if you are having trouble. There is also no reason you can't just play the song you are best at 50 times, aside from the boredom it would be likely to cause.

Complete Stage 5

Earn enough microphones required to complete Stage 5 of the career. It is the final stage and upon completion you will unlock Expert difficulty, which is required for 2 achievements later on. Progressing through the career will also unlock previously locked challenges.

TIPS FOR CAREER: I hate to use the line that a lot of these guides for music games tend to use, but the only way to really get any better at this game is to practice. The game is very accurate, especially at telling what you are saying, which has a direct impact to your score. So you need to say the right syllables and at the right time. This can be especially difficult at the "Singing" parts. I am used to Rock Band and Guitar Hero, and in those games you can simply hum. That WILL NOT work in this game, as you will get a horrible score for "Lyrics" points.

To be 100% honest, the only part of the game that gave me any problems were sections where there were only one or two words to a phrase, the two that come to mind are Salt N Pepa's "Push It", and Public Enemy's "Fight The Power". It seemed I could never hit those two-word sections ("Ah, Push It" in one, and "Fight The Power" in the other). I realized it was a calibration issue with the mic, and it seemed the game expected me to say the words at awkward timing. Therefore, what I found to make it work was to say the first word in the phrase repeatedly, very quickly and start a bit before you think you should, and then finish up the phrase. The game does not deduct it seemed for the extra words. So "Fight The Power" was actually said by me as "Fight Fight Fight The Power". It seems weird and counter-productive, but if you are having TONS of trouble with those like I was, this may come in handy.

Lastly, keep in mind that difficulty level does not affect the career AT ALL. You can play on easy and earn every one of the 20 "Career-Based" achievements. The challenges are the same. The number of points needed for 5 (or 15 for endurance challenges) mics will drop as you lower the difficulty, so there really is no plus-side to doing this entirely on Medium or Hard. If you find something too tough, drop to easy! This is important, especially because the "Microphone Fiend!" achievement requires you to get maximum mics on EVERYTHING, without any room for error at all. This means that one mic short on one song WILL stop you from obtaining that 70.
Fly High, No Lie

20
Complete all High Score challenges

For this, you must simply complete all of the High Score challenges in the career. High Score challenges require simply obtaining the highest score you can. 5 Mic scores are not required, but you WILL need to earn 5 Mics if going for the "Microphone Fiend!" achievement. There are 2 High Score Challenges in the game. The first is Ice Cube's "It Was A Good Day" in Stage 1, and the second is Outkast's "So Fresh, So Clean" in Stage 5. Complete both, and the achievement unlocks at the summary screen of the second one completed.
Always On Time

20
Complete all Timing Challenges

For this, you must complete all of the Timing challenges in the career. Timing challenges require simply obtaining the highest score you can. 5 Mic scores are not required, but you WILL need to earn 5 Mics if going for the "Microphone Fiend!" achievement. There are 3 Timing Challenges in the game. The first is Young Jeezy's "Put On" in Stage 1, the second is Slick Rick's "Children's Story" in Stage 4, and the last is Twista's "Slow Jamz" in Stage 5. Complete all three, and the achievement unlocks at the summary screen of the final one completed.

The hardest of them is Twista of course, and the only real strategy here is repetition. After enough tries, you will know the words, even if they do come at a ridiculous pace, and then it's a combination of skill and luck to hit enough syllables in a row to nail down the 5 Mics. It took me 12-15 tries, but the segment of song is short.
It Ain't Trickin' If You Got It

20
Complete all Multiplier Challenges

For this, you must complete all of the Multiplier challenges in the career. Multiplier challenges require simply obtaining a 4x multiplier and keeping it for a series of sections. 5 Mic scores are not required, but you WILL need to earn 5 Mics if going for the "Microphone Fiend!" achievement. There are 3 Multiplier Challenges in the game. The first is Ludacris' "Stand Up" in Stage 2, the second is T.I.'s "Live Your Life" in Stage 3, and the last is Nelly's "Hot In Herre" in Stage 5. Complete all three, and the achievement unlocks at the summary screen of the final one completed.
Too Hot for T.V.

20
Complete all Platinum Power Challenges

For this, you must complete all of the Platinum Power challenges in the career. Platinum Power challenges require simply obtaining Platinum Power in as few sections as possible. 5 Mic scores are not required, but you WILL need to earn 5 Mics if going for the "Microphone Fiend!" achievement. There are 4 Platinum Power Challenges in the game. The first is Yung Joc's "It's Goin' Down" in Stage 1, the second is Biz Markie's "Just A Friend" in Stage 2, the third is Kanye West's "Gold Digger" in Stage 4, and the last is Diddy's "All About The Benjamins (Remix)" in Stage 4. The achievement unlocks at the summary screen of the final one completed.
Steady Chasin'

20

Endurance challenges require getting as many points as possible on three consecutive songs, with points and multipliers carrying over to the next song. 5 Mic scores are not required, but you WILL need to earn 5 Mics if going for the "Microphone Fiend!" achievement. There are 3 Endurance Challenges in the game. They are located in Stages 2, 3, and 4.T he achievement unlocks at the summary screen of the final one completed.
On The Road To Riches

40

There is 1 New Song Challenge on each of the 5 stages, and some combination of 3 others on each stage as well. See the respective achievement description for each type of Challenge. Once all 20 Challenges are completed, the achievement will pop on the final summary screen.
Perfection is Perfected

30
Get 90% or above on pitch, timing, and lyrics while playing any song on HARD difficulty
(2)
One of the hardest achievements in the game, as you need to be able to do the singing parts. You need to have 90% on all three graded parts on Hard difficulty, which means you can't simply hum for the pitch, as that would neglect the lyrics. One recommendation would be "Gold Digger", as it only has the one singing part at the beginning, and that singing part is short enough that you could hum it, then go back to rapping the rest, and if you do well enough on the rapping, you'll still hit 90% on Lyrics. Another option is "Scenario", as it has one singing part in the middle, and it is literally only one word, with unchanging pitch. It's a matter of preference, and WILL take practice and patience.
Immaculately Polished

20
Upload an "Off The Chain" performance to the Community

See achievement description for "Ain't Scared to Share It".
We Are The Best

20
Complete a Duet earning an "Off The Chain" rating with both players on HARD difficulty

For this achievement, you must be on hard difficulty, with two mics connected. Choose "Play" and then "Party" from the main menu. Now choose a song, and on the difficulty select screen be sure you change from "Solo" to "Duet". Now perform the selected song as you normally would, but do it into both mics at the same time. Be sure to select a song with only rapping parts, as it would be tough to sing and rap at the same time. "We Fly High" is short, easy, and only has rapping parts. If you get 5 mics on the song, the achievement will pop at the results screen.
All Eyez On Me

10
Get at least "On Point" on a Solo on EXPERT difficulty with the original vocals turned off

Expert difficulty is much harder than Hard, only because none of the words scroll along the bottom. However, you do still have the artist's words being spoken under normal circumstance. This achievement however, requires you to turn vocals off at the difficulty select screen before the song starts. This leaves you with only the beat and the little balls that indicate a syllable needs to be spoken.

The easiest way to get the 3-mic rating needed here is to load up youtube and find the video for the song you'd like. I recommend "We Fly High" or "It's Goin' Down" but that is personal preference, as the songs are familiar to me. Make sure the video on youtube matches the one on screen, and turn your computer volume up. This will at least give you the artist singing to be able to sing along to, which won't make it so bad. The reason I recommend "It's Goin' Down" is because the video has a long intro that you can use to match the song up to without missing any words. Make sure to get three stars, and the achievement will pop at the results screen.

NOTE: If you manage to 5-mic it instead of only 3-mic'ing it, you will obtain the achievement "Seal the Deal" at the same time, thus saving you one attempt on Expert.
Stuntin' is a Habit

10
Get a combined 2,000 views for all your uploaded videos

First, be sure you have loaded a video to the Community. Do this early in career so that by the time you finish the video can be found in the "Community" section of the game. Now load up a second profile, and go into "Community" from the main menu. Find the video of the profile you want the achievement on. Now press to bring up the Video, and then back out with . You need 2,000 total views. You will have to load the profile you want the achievement on after reaching 2,000, and the achievement will pop on the main menu. Note again that you DO NOT need to let the video load.

Thanks to dreadheade for confirming that the 2,000 views CAN be your own profile as well.

Perform a Duet where you score 50,000 points more than your friend

This achievement can be done on easy. Choose "Play" and then "Party" from the main menu. Now choose a song and on the difficulty select screen be sure you change from "Solo" to "Duet". Also be sure to have two mics connected. Now perform the selected song as you normally would, and let the second mic simply sit there. As long as you score more than 50,000, you'll have 50,000 more than them, because the mic was doing nothing the whole time. The achievement pops at the results screen.
Towering Over The Competition

20
Perform a Battle where you score 50,000 points more than your opponent

This achievement can be done on easy. Choose "Play" and then "Party" from the main menu. Now choose a song and on the difficulty select screen change from "Solo" to "Battle". Also be sure to have two mics connected. Now perform the selected song normally, and let the second mic simply sit there. As long as you score more than 50,000, you'll have 50,000 more than them, because the mic was doing nothing the whole time. The achievement pops at the results screen.
Close Call

5
Win a Battle by less than 1,000 points

This achievement can be done on easy. Choose "Play" and then "Party" from the main menu. Now choose a song, and on the difficulty select screen be sure you change from "Solo" to "Battle". Also be sure to have two mics connected. Now perform only the first couple of words from the song into your own microphone. You should only earn a couple hundred points. For the rest of the song, simply remain quiet enough that no sounds register in either mic. There is no fail, so the song will finish out and you will win the battle by the couple of hundred points you earned at the beginning. The achievement will pop at the results screen.
Chain Reaction

20
Get "Off The Chain" rating on all songs in a playlist containing 5 or more songs

See achievement description for "Go The Distance".
The Voice Of A Generation

10
Get "Off The Chain" on the Solo version of Gold Digger

Off The Chain requires a score of 5 mics. "Gold Digger" is a very easy song (in Stage 3) with the exception of the first singing section by Jamie Foxx. However, once again this achievement can be obtained on easy, and 5-mic'ing this song is a necessity for the "Microphone Fiend!" achievement.
Rhymes Are On Time

10
Perform a Battle where both players hit 25 rap targets in a row, at the same time

Choose the song that you know best. Choose Easy difficulty, and change "Solo" to "Battle". Now rap the song as you normally would, but do so into both mics at the same time. Both mics are looking for the same words at the same time in Battle mode, so all you need to do is hit a 25 beat streak. Because you are operating both mics, the streak will count for both parties at the same time. The achievement will pop at the results screen.
No Competition

Win all songs in a Battle playlist containing 5 or more songs

From the main menu, choose "Play" and then "Party". Create a playlist of 5 songs, and on the difficulty select screen be sure to change from "Solo" to "Battle". Launch the playlist and set the second mic on the ground. Play the 5 songs as you normally would into your own mic, and you will be sure to win all 5 songs. The achievement will pop at the results screen for the final song.
I Keep Blowin' Up

Activate Platinum Power 4 times in one song

This can be done on easy. Keep your multiplier up, and fill the Platinum Power Meter by hitting extra "Rap Beats" after it is already full. Any notes hit above and beyond what is needed to fill the meter will add to the Power Meter, and when it fills it will activate itself. Do this four times in one song, and the achievement will pop at the results screen. A good song is "Fight The Power", as it is Stage 1 and VERY long (7+ Minutes).
Ain't Nobody Dope as Me

Get a "DOPE" lyric rating on every phrase in a song

This can be done on easy. Choose a song that you know the words to absolute best. Don't focus on Pitch at all during the song, as the two are scored entirely separate. Do however, be sure to say the correct words DURING the pitch parts. Now be sure you are saying the correct words, and assuming you are on Easy and choose a song you know, this should not pose too big a threat. This popped for me on my third or fourth song, on hard difficulty, and I'm no Twista, so it shouldn't be too bad.
I Make This Look 'Eezy

Get at least "On Point" on one song from Lil Wayne and one from Kanye West

This achievement will already be half done once you complete the "Voice of a Generation" achievement. You simply need to 3-mic a song by both of the above artists. You will already have "Gold Digger" done by Kanye West in Stage 3, and you will come to "A Milli" by Lil' Wayne in Stage 3 also. This can be done on easy, and should not pose a threat to anyone. This achievement is also unmissable if going for "Microphone Fiend!", as both of these will need to receive a score of 5 mics to do so.

On Point requires a 3-Mic Rating at the end of a song. This should be no problem, considering it can be attained on easy, and you will play far more than 5 songs which were released before 1990 throughout the career. This is guaranteed along the way to "Microphone Fiend!" and cannot be missed.

Unlock all locked content in Career mode

This will be unlocked while attempting the "Microphone Fiend!" achievement. There are 85 rewards to be unlocked, and they are only unlocked by obtaining mics. It unlocked for me after obtaining roughly 300 mics of the possible 305. You can check the progress of this by going to the main menu and selecting "Extras" and then "Player Stats".
