Since soundclick keeps experiencing technical difficulties, are there any other sites that you guys would (or do) have your music on?

I posted my link on another board for the first time and a few hours later, soundclick's server was too busy.

Ok, I know there is Vitamin something, that clear channel one, and a few others I've seen, but I can't remember the names.

www.IUMA.com -- but the interface is CRAZY and I'm still not sure if they ever actually posted my songs.
