What does Google know about entertainment promoting? That's what production is now; it isn't just as easy as putting up a ton of music on YouTube, 90% of music promotion is telling people what to like, and Google has shown very little skill at consumer marketing or trendsetting; just because they know how to get millions of people to use free stuff doesn't mean they can figure out how to sell people coolness, hipness or identity. You suggested they market music, and "selling cool" is what marketing music is.
This sounds like a job for Apple!
The end of labor is to gain leisure.
