Elaine, if you see this, can your remember how iCompositions dealt with albums? I don't think you could upload a whole album in a batch, but couldn't you somehow package and sell a group of songs as an album? I never used that feature, so vaguely remember something about it.
There was no way to group songs in iComp -- it was very rudimentary in that regard... you just uploaded songs. Making playlists would be a great feature in the future.
John Cupcake is correct as far as uploading individual songs. You're right Doc...there was something in the promotion feature that allowed CD's to be purchased. I'll search my archives :)
