Audiosurf
Audiosurf is a game that's been out for a few years now on PC and recently had a sequel come out on steam. It retails for about $10 USD and uses your music to procedurally generate levels for you to play. There are 14 modes to play across 3 difficulty levels as well as online leaderboards. In this video I just played the basic mode across all 3 difficulties because I'm not coordinated enough for the other ones.
