Live music industry is also bigger than it's ever been. Obviously not so much this year but booking fees for big artists run into the millions. They also get paid to feature in other peoples' music/content, and then again for access to their built-in promotional/marketing networks. They're selling hype. Anyone focused on milking profit out of the actual recordings themselves is stuck in the past, for the most part.
The modern model is to share the music freely as it serves primarily as a sales pitch for the artists brand. Young people want something of "value" for their money and they don't see a recording itself as having even $0.99 of value (even though they've mostly forgotten how to actually pirate media), like shitty overpriced merch and miserable "live music experiences" and "meet and greets".
Really what they're selling is hype. Which explains why an extreme manic depressive like Kanye has been so successful in this context. It's a system that directly rewards con men and effectively punishes any kind of caution or prudence. It also rewards drug addiction as many of these con men rely on drugs to maintain the illusions of their existence.
It's particularly sad because this system exploits the earnest passions of both the artists and the fans to manipulate them into participating.
