What sites, like mp3.com, offer a lot of free music offered up by the artists (that is, morally clean)? Preferably with a large selection. See, I like to hear folk songs and standards a lot, but as I am morally opposed to file “sharing”, I find it difficult to find such mp3s. So any suggestions? 
I just moved a bunch of my stuff to www.besonic.com, they seem to have a good selection. I also have stuff on www.soundclick.com.
