Spotify + extreme bias towards X # of artists due to rights ownership = potentially crap experience for listeners.
I was thinking that if Spotify kept the same experience for listeners that they had now in order to grow their subscription base, and just reported higher earnings for the artists they had signed versus ones signed to a 'different' label, that over time as contracts came up for renewal people would move over to Spotify.
Good content is good content. For music - it's even better if it's not yet well known because for some reason people think more highly of themselves for being an early fan. Early discovery favors audio moreso than video. So pushing originals (newly signed artists) is a great strategy for Spotify. So long as it's good music.
Mind you, I don't like video being fragmented but that's a more deliberate choice a lot of the time for me. I'll subscribe to a few places based on available and original content--somewhat grudgingly to be sure--but I accept those are my options.
