I suppose the techno music on Exit Path. The music on Flight is good too. I don't really listen to it though. I just pull up my playlist on myspace or just get my Ipod.
I think that the best music ever can't be by anybody but Kevin MacLeod. I vote for his "Sad Trio" from Small Worlds by David Shute. I play it on the piano when I feel happy or sad, and it provides great enhancement to emotion.
