Learsfool, that was my attempt at humor. I've never heard of cool classical music. I really meant any classical music you like.
Since I have jazz by Andre Previn, I tried to find some classical music by him, but this is all I found.

Maybe you could find some classical music by him and paste it so we can hear it. Or any classical you like best.
Enjoy the music.
