If I listen to music before going to bed I can't sleep

if I listen to my iPod before going to bed I won't sleep the whole night why???

This is called Insomnia what happens is your brain, doesnt want to shut down, so what im saying is pretty much is that mabey you should take a relaxing bath after listening to your music so your body will be shouting SLEEP! instead of ROCK-ON! Good-luck.

What kind of music?

maybe because you keep thinking about the lyrics?
I find that if I listen to music, I can still sleep.
maybe listen to some soothing, quiet music =)

I listen to metal and sometimes hip hop and I fall asleep within an hour
I don't know it could be insamnia or you havent found the music that makes you sleep the whole night.
