The real value in Spotify is the music discovery. That’s driven by data that very few are in a position to collect. Of all the big tech companies, Spotify is the only one I can think of that uses the data they collect from the users to give the users a uniquely better experience. Even YouTube is littered with promoted ads and videos. If you’re avoiding ads anyway, it’s a win win for the user to pay for Spotify premium.
Then you can do what you will with all the playlists you make.
