It's more or less the case that all the music streaming services have all the music, so you can pick the one that offers the best balance of price, features, and other things like amount of money they pay out to artists, and then listen to whatever you want. That works pretty well for consumers, and streaming services don't get to dictate what music gets made.

TV and movie streaming services have basically ended up in a situation where everything's on exactly one service, and you need to pick which ones you pay for based on which have the things you most want to watch, even when that means tolerating an interface that barely works or annoys you with ads or trailers for things you'd never watch. This works fairly crappily for consumers, and streaming services pick everything.

Video game subscriptions seem to be going for the latter approach, and so overall, things are probably going to suck. Hopefully, nothing important ends up solely available via subscription, though, and experiencing the sucking remains opt-in.
