> (That's probably partly why music streaming services don't compete on content; most people don't care exactly which funky music they're listening to as long as it is funky, and had most of the popular stuff. But they definitely care if they want to watch Stranger Things and they can't watch Stranger Things but maybe you're interested in these other crap knock-offs?)

Idk. I can imagine an alternate universe where Taylor Swift's new album was exclusive to Spotify. All the Swifties using Apple Music probably aren't interested in "Taylor Swift knockoffs".

It's not entirely obvious to me why this hasn't happened.
