If I understand this right, If I only wanted to put up singles to sell as downloads from ITunes, Napster,etc. it would be better to use your service, but if I had a physical CD to sell on line, it would be better to go with CD Baby, who could get me on download sites and sell my CD and do the shipping and take payment, etc.

I'm sure there is room for both services. If I had strong single songs to sell and did not want the cost and hassle of doing a CD, your service would make the most sense. Is there a minimum number of songs that these upload sites will accept per artist? How do they display them to the buying public?
