A lot of this is a massive stretch. It's majority self-hosted which the average person is not going to deal with.
Some of the "alternatives" aren't even close. All but one of the Spotify/Apple Music replacements are self-hosted things where the user needs to provide the audio files. That's nothing like the near-infinite jukebox experience that Spotify and such offer. The only one that isn't self-hosted/BYOM is basically just an app-only (no web) front end for free YT music or you need to pay for the underlying streaming services anyway.
