Music is consumed differently than TV/movies.

People these days usually don't listen to entire albums, but to individual songs as part of playlists. If all record labels created their own streaming services, it would break this experience and people would go back to piracy again to get it back.

Further, music is something that usually exist in the background while people do other things, whereas movies/shows requires attention to benefit from the content.

Service like Netflix or Disney+ can manage to create exclusivities because people watch episodes of a show in sequence due to the nature of the medium and are emotionaly engaged/invested in the story/characters, so they are essentially "captive" of that serialized content for its duration.
