In any Battle get an A for Scratching, a B for Taps, a B for Crossfading and an A for Freestyling.
There is no sure fire, concrete way to obtain this achievement. Different songs require you to miss a different amount of notes to get B's for Taps and Crossfades. I managed this on the Timbaland mix for "Way I Are." What I did was miss around 30-40 Taps and was intentionally late on almost every crossfade. I did this during a checkpoint battle online.
If you have the other player simply lay down in defeat, you can get this within the first 7 checkpoints and it takes around a minute and a half. It's not the most difficult in terms of skill, but it definitely will allude many a player.

I did this on Heartless/Lovegame expert. I don't have a surefire way, but my general strategy was to skip every tap and crossfade, trying to hit everything else, until the first freestyle crossfade. After that, try to hit absolutely everything. I would randomly skip groups of fades/taps until I felt confident with the rating. Took about 4 tries to get right, you need to get a feel for what gets you a B on taps and crossfades.
"hey guys there is an easiest way to get this trophy!look,i have 2 dj hero turnatables and i found an easy way to get this trophy.connect ur turntables on ur ps3,360 or wii and then go to battle and choose checkpoint battle. choose the mix snow 'informer' vs jackson 5 'ABC'. for the first 2 checkpoints DO NOT DO ABSOLUTELY EXCEPT THE SOUND EFFECTS! after the 2 checkpoints do EVERYTHING right and DO A GOOD FREESTYLE. tht will unlock? the trophy!

I tried it with that mix on a checkpoint battle following what we wrote and I got it on my first try, so believe him!
I got this on Mo' Money Mo' Problems on Medium. The song is heavy on scratching and low on crossfading and taps. Do nothing but scratching for the first three checkpoints and from there on make sure you hit all of the taps. Hit all of the crossfade but completely skip the crossfading in the chorus. The tricky part to this is the freestyling crossfades. I kept it on the left but hit the right for the drum hits and alternated, if that makes any sense.
It's the most guaranteed way I could find getting ABB, the last A is the only one that gave me a little trouble. I got B for freestyling five or six times before figuring it out.
I just got this on my first try going for it. haha.
I did it on The MessageJungle Boogie on expert in an offline checkpoint battle against a second turntable. If you have one, do it in Checkpoint, so the song is over in 7 checkpoints, that way it will go faster, and basically, just nail every Freestyle and craches, and purposely miss alot of taps and almost always go late on crossfades.
