So what do people think of my idea mentioned above?

An idea for generating income right on this site is to sell members' mp3s with Mudcat getting a cut. See eFolkmusic.org for an example. So many mudcatters are musicians and have music available for sale. Not all of it is available at Amazon, but could be available on mudcat to each other as well as to the public. This would be good for members and good for the 'cat.
