To make things worse, they flood you with constant new content while you browse. It feels overwhelming to me. It's sort of an ADHD nightmare.
With Apple Music, at least, I keep a clear distinction between my personal library and the rest of their offerings. That at least gives me a sense of shape and dimension to my library. To be clear, my personal library is a mixture of music I have bought and music I added from the AM library.
To do this, I unchecked "Add songs to library when adding to playlists." This makes Apple Music not add every single song in every playlist you follow to your library.
Now, I can browse my curated selection of music and playlists, OR I can play music from Apple's playlists, etc. When I discover an artist I like, I can then purposely add it to my library.
I wish I could do this type of curation with Apple News and Apple TV.
