"In Uta Kumi 575, two high school friends have dreams of making it big in the pop scene. You’ll help them do this by tapping the screen and rear touch pad in time with their music. Anime fans may recognize the name for its relation to mini-series Go! Go! 575, but one need not be familiar with the show to have fun with the game." -PSLS
I'd play that.
Sega cranking out dem Vita music titles.
Sounds like a fun game.
