Spotify's biggest enemy are the record labels that they have to pay license fees to. Slowly ramp up the AI slop while ramping down the label-owned material and hope subscribers don't notice. It's a play that worked for Netflix, which used to have every major show a decade ago and is now majority mass-produced Netflix Original slop.
I noticed music in TV shows is AI slop so they don't have to pay licensing fees lately as well. I was watching Unsolved the series about the Notorious BIG and Tupac murders a few weeks ago and in one of the club scenes a "Biggie" song that I'd never heard of was playing in the background, I wasn't familiar with that song so I googled it and it was an ai Biggie inspired recreation, not one of his actual songs.
The Beavis & Butthead and Daria shows in the '90s also used a lot of licensed music. When the DVD versions arrived in the mid-2000s, the music was removed and replaced by stock instrumentals; I'm not sure the torrents of the original versions are even being seeded anymore.
