i recall reading an article in the guardian or some other newspaper about some basically unknown companies that contract musicians to create stock background music for television. what was interesting is that they now create hyper-specialized music and ambience, which is then picked up by spotify for curated playlists. they create basically filler content, and for some reason these genre/mood playlists generate enough revenue from casual listeners so it is a worthwhile niche, and i guess that ai-generated music is the natural progression from that.
edit: it might've been this wikipedia page and some swedish newspaper i had read. i specifically remember Epidemic Sound, as the swedish state television sometimes uses them for stock sound.
