Music is my caffeine, I have never been able to fall asleep to music. I'll just lie there and take it all in and analyze it musically...I tried to fall asleep to the classical station for a while but I kept staying up until three or four because they'd play an awesome piece, usually a long symphony and I would listen to the whole thing. That's another caveat to my listening habits, if there's anything that I like that I hear on the radio I'll do anything to be able to finish it, whether I'm in the car, with friends, at home etc. It's not a terrible thing, but it's an interesting idiosyncrasy
