So I just recently got this game Audiosurf... it's pretty neat. It could sort of be described as a cross between Tetris, F-Zero, and Guitar Hero... sort of. Anyway, the point is, that it's compatible with .ogg files, so of course as soon as I read that I went straight off to play the PlaneShift soundtrack in it. It works out pretty well, and definitely gives you a new appreciation for how great the music is in PlaneShift, when you're playing a game that goes along with it...
