It would at least be better, than sneakily trying to substitute it for artists they'd actually have to pay royalties to, yes

One big difference is that these shows and movies are not "ghost," they credit their crew and talent like any other production, and those folks negotiate their pay rates similar to other productions. If you are a grip on a Netflix original movie, you will get listed in the credits like any other movie.

The other big difference is that TV and movie productions have always been "assemble when needed." Production companies are typically very thin business shells who hire in 99% of what they need per show. As opposed to a band or artist like Taylor Swift or The Rolling Stones, where the core persistent business unit is the talent itself.

The difference is how they're consumed you don't sit down on Netflix and say "put some scifi on shuffle for 8h", you sit down and choose a show.

If you're the kind of person who would manually queue up 100% of your songs for the day then Spotify Generic songs aren't an issue. If you just hit a "2020s R&B" playlist and go that's where it feels more sketchy.

Good point. Music is much more personal, perhaps?
