Download free music (legally!)

I need to plug my latest interweb discovery, Epitonic. It’s a streaming/downloadable music web site with a ton of really great music, mostly from independent artists who have made some their music freely available rather than play the major label/RIAA game. It’s free, it doesn’t require an invasive registration process (none at all, actually, unless you want to save playlists), and it’s not choked with obnoxious advertising. I’ve been listening to it all day.
