that you can just go to and simply listen to any kind of music? ie.. look up the singer and then the song and then listen to it and not have to buy it or download it.
magnatune.com is another good one. You can listen to their library for free or down load the music for a variable donation of which the artists keep half!!
Imagine that. Artists getting dollars for their music not pennies. Very progressive. The music is really good too.
