The major labels invested in Spotify to help kill illegal downloads and control their future during the transition to streaming.
Now, with competing services, they want to make sure Spotify doesn’t become dominant and control their future.
Why can’t Spotify just remove the label as the middle man and give artists a bigger chunk? That would attract artists and Spotify gets to increase their share a bit as well.
Isn’t a label just a glorified pimp for an artist?
For ambient/classical music Spotify is already doing it. Placing an order on music they believe their subscribers would like from unknown artists.
