DMcG,
I don't know about Emusic, but EFolkmusic just picked up my band, and it's a pretty good deal. I set the profit I make on my CD's, and it gives me a chance to sell "singles" on the net with none of the work or hassle. They split the .99 mp3 downloads 50/50. The name bands are going to do the best with this deal, but they promote all the artists pretty well I think. Best of all, they send payments every month (joy, joy)
