Ok, since you asked...
..not something you'd want to try I'd imagine...
Yen Town Band: Montage
...which is a band formed for the Japanese film "Swallowtail Butterfly"
most of it is sung by my favorite singer EVER, CHARA.
I don't speak or understand a word of Japanese but I like to listen to music in other languages. People sometimes have this idea of what it would be like but they are almost always wrong.
I dislike heavy metal, rock and rap mostly. I can't go without listening to my ipod/cd player while working out though, just can't do it. Music is so filled with anger and hate these days, so I tend to avoid most american alternative rock or whatever you call it.
I also often listen to Pearl Jam, Radiohead, some Nine Inch Nails (when i'm in the mood), Ayumi Hamasaki and others.
I've found that the best music to listen to for a good workout is GOA Trance, but you have to be into that sort of stuff. Some of it is really BAD. I've always liked astral projection though.
