To vastly oversimplify, there are typically four stops in a revenue chain. (For more specific details about how particular revenue streams work, see the Future of Music Coalition’s series of charts here.) Consumers pay a service, the service pays labels/publishers, each label/publisher pays its musicians. But each step of this chain is shrouded in some form of obfuscation. Consumers see a sticker price on the service—their $10 or $15 or $20 a month—but revenue also goes into the services from advertising, and services can be cross-subsidized by their parent companies’ other businesses.
