Okay, I just bought it today and I can fully back up JKTrix's claims. This game, while quite challenging at times, is crazy fun. The beats you have to hit fit in perfectly with the songs, and the zany stories are pretty amusing at times. However, sometime the difficulty is too frustratingly hard (for me, at least). I'm currently stuck on (what I believe is) the last level on " Cruisin' " difficulty (SPOILER)(the level where the aliens have banned music and are turning people to stone) and can't get past the first twenty seconds of it, so I'm just trying to get an "S" rating in the other missions.
