Pretty darn good! – TunesHolic Review

UPDATE: This game no longer works. Whenever trying to play I select my song then the app immediately crashes every time. Please disregard previous good review. One of the better best games out there! Has original music plus the ability to use your own music. Beat detection with my own music is the best I've found out there. It's super easy to earn points as well by playing the game. Which is awesome!
