With Apple Music you can add your privately owned music to the library too. It even outdates Apple Music with a now legacy service called iTunes Plus that allowed you to stream your private music collection with iTunes from ‘the cloud’ for €25/year. Back in the day I even used this to ‘white-wash’ low quality mp3 files to 256kbps acc files instead. I think it is actually user-hostile to force users to pay for YouTube Music when you want access to ad free YouTube videos, probably why in Europe YouTube Premium Lite exists (without Music), because tie-in purchases (translated term) are generally not allowed here.
