Sounds like a great idea LJ, you can count me in. I like to learn about new artists, but since I'm on slow dial up it's hard for me to get songs people just list, legal or otherwise.
I tend to listen to mainly Johnny Cash, the man has such a diverse song inventory its easy to find something to fit whatever mood I'm in. Although Clutch (come on MF) is not bad for those 'I want to beat the living crap out of the next person the speaks' mood I sometimes get.
