I think in the particular case of music the market is saturated by an abundance of
human generated content, not machine produced.
Music is one of those human endeavors where it is very desirable to succeed, to the point where many people are willing to do it for free for love of the craft. I can't see the immense profits Spotify allegedly makes by exploiting the artists.
Perhaps we need to accept that the artists are not so much getting shafted, but simply that the age of the superstar is over and most music will be free.
