Ahhh, music to train to. Some of the posts mention techno, drum n' bass, industrial, and Rob Zombie. Research into BPM(beats per minutes) shows that music can alter brainwaves. My thought is that some musics can induce a trance state that is similar to the state of consciousness of meditation. Personally I find music between 160- 180 BPM gets my chi flowing, and I'm in a more "energized" condition.
The Japanese have a musical tradition of drumming that I heard years ago and was blown away by. The music carried me right into a clear, zen state. I think it was Koto, Kodo, something like that. Awesome stuff!:hammer: :boing2: :hammer:
