Very cool game design, and tons of fun to slice notes and stay active. Blows guitar hero type of games away, as far as fun factor is concerned. However; the music is completely bogus. Songs that nobody knows. They offer songs that people know, but you can only purchase them at a ridiculous price! Offer some popular music, as part of the game purchase, bring the prices down on music packs, and then I'll give this game a 5 star!
