I don't know much about classical music, but I do enjoy it!
When I was a kid, I used to have a really hard time sleeping (still do, a lot of the time). There was a radio station that played classical music and I'd listen to it. It relaxes me enough so that I could fall asleep. It's not really something I do anymore (I'm always paranoid that I'll miss my alarm with the music playing), but every now and again I have enough trouble falling asleep that I have to resort to listening to music
