While streaming music currently gives lots of music for cheap, it is doing because it is competing with piracy. And efforts to control piracy are a bit hampered because of the potential to use the "analog hole" (if you could only get a given song with analog recording of Spotify, then people would do it).

Further, a lot of the anti-piracy impulse is not simply a desire to charge get more money from everyone but a desire for control. Essentially, the music industry is reconciled to most people paying little for their music (or better yet, most people forced to hear advertising mixed with their music) but the industry want to have the ability to sell to people at a variety of levels. Perhaps charge more for just released music or certain artists or music connected to movie sound-tracks or for "audiophile level" audio or whatever.

For a commodity that's infinitely reproducible, the ideal position is being able to separately charge each consumer exactly what they're willing to pay. Maximum utility for the owner, which would imply minimum utility for the buyer.
