Heh! What don't I like??? If I have to choose an absolute favorite, it would be 80's pop/rock. I have far more music in my collection from that era, and most of my favorite artists are from that time. However, that's like saying I love one form of food over another. I love so many different things. My top artists would be The Beatles (number 1 fave, always), Johnny Cash, Elton John, Billy Joel, Weird Al Yankovic, Marty Robbins, and there are so many others that would run close. Admittedly, I'm getting to be an old fogey. While I know some stuff and have some artists and songs I like from the last ten years or so, I am way disconnected to modern music these days.
I could write a huge list of everyone I like, but I should leave some space for everyone else!
