I just got this..it's one of those timing-music games where you pick a track and play til the end of the song and get a score. Since it's in Japanese..it's hard to read the title screens and such, but it doesn't really matter, as the gameply is pretty much unaffected by the language barrier. It's got some classic gaming songs on it, and a story mode and a practice mode. Pretty darn fun. I'm glad my friend brought me this back from japan
