[ This an interesting new online music community site. The tracks are released under a Creative Commons Music Sharing Licence, meaning you can download, share, and trade them noncommercially. That's not the important part though... what's a little different here is that they've built a very friendly interface to the community rating features, with inline players and a rating scale attached to each track, making it really easy to listen and rank the songs.
Artists can, for free, upload 15 megs worth of MP3, hence the name, or they can pay to upgrade to a 50 mb pro account. I'm not sure if their business model is sustainable... seems unlikely, but do check it out, if for no other reason than to play. -k]
