I've been looking into music networks and communities on the net. I'm still on 26.4k dialup for at least two more months, so my participation unfortunately has to be kind of minimal. However I stumbled across somesongs.com yesterday which is sort of like an mp3.com or nowhereradio.com that doesn't provide hosting for your songs. You host the songs yourself and then the website takes care of the feedback and profiles and all that business.
Because I am starved for attention I posted my new song over there and we'll see what happens.
