AudioSurf

Audiosurf is a puzzle/action game where you use your own mp3s to create the level or track, if you're after a sedate casual game go for a slow track like Feist - Inside and Out or if you're up for a hardcore challenge Dragonforce - Through the Fire and Flames should satisfy your gaming urges (shown bellow) it comes with multiple game types and the best thing about this game is that the game grows with your music collection, you can also compare scores with the online leader boards.

Audiosurf is created by Dylan from thebestgameever.com and is due for release in February 2008, I highly recommend this game.
