I have to be one of the Audiosurf detractors here. It was fun, and a very cool idea for sure, but the thing is really pretty repetitive, and the whole "yer palying 2 yor music!" thing is totally bogus. Fine, it might use that data to construct the level, but it may as well be random because even when you can tell that it built something based on a part of the song, it just isn't cohesive enough for it to actually be "cool". It isn't a bad game by any means, and it's a fun diversion which may well satisfy some, I just don't think it deserves even half the accolades it's been getting. It's a decent game with a little bit more depth than appears on the surface, but not as much as it tries to make you think you're getting.
