Living Legend Achievement
Reached the "Living Legend" rank.
This requires reaching Rank 1. You start at Rank 20 and it counts down to 1. You level up ONLY in Perform It! mode. Playing songs in Dance Battle or Break It Down mode do NOT count. After each song your meter will fill up. Your rank will be listed under your gamertag on the main menu. This achievement will take quite a bit of time. Depending on how many attempts it takes you to 5-star every song on Hard though, you may get this achievement by the time you're done.
