This will be the story to watch in the next months: 19 Recordings has sued Sony Music for $10 million:

"Sony’s failures include, but are not limited to, incorrectly calculating products sold, incorrectly paying 19 based on products sold, failing to allow 19 a full and fair opportunity to conduct an audit, attempting to recoup monies not owed to Sony, and failing to account to and pay 19 fifty percent (50%) of Sony’s Receipts from its leasing or licensing of the Masters to streaming services.”

Very interesting. I really wonder about streaming. Spotify has always struck me as a dangerous, Napster-like concept.
