Has anyone used Jamendo? It's a website where artists can submit their music under a Creative Commons license - so anyone is free to download it as per the terms of the chosen license.
The website seems to be having an update right now, but as soon as that's done I'll be having a look around for anything I may like.

All of you who like soundtracks/ambient music will love this: <!-- m --><a class="postlink" href="http://www.jamendo.com/en/artist/dj.fab">http://www.jamendo.com/en/artist/dj.fab</a><!-- m -->
