While I don't deny that the Spotify CEO is the best person to send a message like that, I have to ask myself what life was like for musicians before Spotify (or any other low-paying streaming service).

30 Seconds to Mars made a documentary about the album they recorded in 2008 and the lawsuit they had to deal with at their record label (which had been recently purchased by a larger company that had zero music / talent experience). Their contracts seem to put them almost $1 million in debt to the record label for each album, despite the fact that they sell (err sold?) multi millions and they do worldwide tours.

Sure, Spotify's CEO is a strange vessel to make more demands on musical talent, but he's also in a position to know how his customers want to consume their music and what gets them engaged in his product. I would take it for what it is and no more.
