imeem.com is exactly the site you're looking for, in some ways it's like youtube but you can upload mp3's, there's no limit to the amount you can upload and anyone can listen. It also gives you a nice player that lets people incorporate your tunes into their playlists or feature them on their profiles.
If your an artist it has one very special feature, you can register your music with snocap, and then imeem will share 50% of the ad-revenue your music generates with you. That's a a whole 50% more than myspace ever offers to artists.
