Lots of VCs/investors say not to do anything that touches music, specifically major label content. Dalton's big talk at Startup School is an example of the (reasonable) position against doing music startups. I've heard it from lots of people who I have talked to anecdotally.
I guess I was thinking of all the cool things bandcamp (which I love) and soundcloud are doing for indies, not to mention Spotify, rdio, grooveshark, itunes, amazon music, and google play.
I've been looking at the space and don't really know what I could add. It looks really crowded with innovators to me. If I read you right, you're just saying that there's still room for something better?
