Thanks for those; the audacity of the major labels, in conjunction with politicians, to close down/make more difficult avenues for the free trade of music adversely affects those of us who are in it for the music, as opposed to whatever it is the labels are after.

there are also:
soundclick
Iuma
Music Builder
StationMP3

All with ways to stream/download mp3s free, from people who actually WANT people to listen to their music.
