Lately, I've been listening mostly to Gospel because I can find many sub-genres in it. I listen mostly for the words of encouragement but the different styles suit my moods quite well.
Last night I listened to one, that if I stopped listening to the words and concentrated on just the music, I could picture myself in a smokey corner slow dancing.
But then again, one of my favorite groups really rocks and rolls with their songs. The leader of the group is quite a dancer. LOL They have a good bit of choreography with their singing. LOVE to watch them!
I also like classical, the Moldy Oldies of the 50's, a very limited amount of the older C&M but not the ones that sound like sick cows dying!

Shania Twain was good until she (the person) started making me sick to my stomach.

I don't really consider her music C&M, though. Rock a Billy?
Yes! You bet music is a huge part of my self-help!
