Publishing Music Online

hey guys, not sure if I have the right forum for this question, but I have a friend who makes great music.  I'm trying to get him to publish his stuff online so people can buy it - it sucks that he creates all this great stuff and not very many people get to enjoy it. he's not sure where to go, or how to even get started. I told him I'd check around, and I thought I'd start here.

thanks, in advance


soundcloud,beatport and itunes are the best


Also bandcamp.
