Labels are part of it, since the major music labels control just about everything of the artists signed to them. And the 3 big labels all signed on with Apple Music but the details of what the labels themselves get will likely not be disclosed. Apple may or may not be engaged in tying. Some indie artists report Apple threatening to boot them from iTunes if they don't sign on to Apple Music. Google did something similar with YouTube a few months back. Independent musicians have almost no power or money in the industry, so they're stuck taking what they can get for the most part.
