With “Show Apple Music” disabled, two of the three sections in Music.app are filled with almost nothing but Apple Music. Sure, Radio might be free, but it’s still Apple Music. To quote a great Westerosian thinker, “I don’t want it”. I want my own music. Nothing else. There used to be a way to remove Radio via parental controls, but even this hack seems to have been removed since at least iOS13. The categories in the third screenshot are all 100% Apple Music, nothing in there is coming from my local music library.
