I think the biggest problem would be the piracy caused by only releasing music on one retailer. It would also cause difficulty for fans (I use Rdio and have to switch to Spotify just to hear the new album from a band I like?) which is something I doubt musicians want to do.

I would think there's no reason not to release it everywhere (I assume syndication will eventually happen to netflix produced content because why leave additional content revenue on the table?)

Thx for sharing. Any stats on how the funnel works in music vs movies/shows? I assume the same percentages apply across content (roughly) in terms of bands signed - > platinum records for music, vs. movies greenlighted to record shows for movies.
