What EternlRayne said! Would definitely love this ability as well!
To Eternl Rayne,
The only thing that I could see as being a problem would be your suggestion to include the ability to upload photographs directly on the marketplace. Unfortunately, if Zune doesn't have permission from the artist or their representatives, then that could open them up for copyright ifringement suits. The ability to upload pics and bio by the customer wouldn't be a problem for them so that should definitely be something they should think about. I, like you have quite a few artists in my collection that have no information associated and would like to be able to enjoy something other than a black background...
