I picked this up cheap the other day on Steam's weekend deal and I'd definitely recommend getting it while the deal is still on. It's loads of fun, and really addictive; Basically, It's a racing game where you drive a ship along a track and pick up coloured blocks , trying to match three or more for points. But, you can choose any music track on your computer, and the game designs the track based on that song. The faster the music, the faster you move, the heavier it gets, the more the track shakes and curves, etc. It's worth it just to play "Don't stop me now".
