How you can bookmark music/playlists/curators/etc.
There is an old locked qna here with the above question and below answer.
To bookmark stuff in Apple Music, go to the Share option - the box with the arrow - and select Notes. That's pretty much it. When you open the Note, you click the link in it and that opens that page in Music. This works because iOS allows apps to communicate using urls; it's called x-callback-url. Example: I read that BBC Music is now a classical music curator so I found that page, clicked on playlists and shared it to Notes, put it in a folder I made called Music in Notes, and now I click on that link and the curator page opens to BBC Music's playlists. This works for anything because each thing is a url and can be passed from app to app. So think of Notes as your bookmarks.
This does not work if you are listening to a PLAYLIST because the url link takes you to the track in the original music recording album. The way I deal with this is to take a screen shot!!
Come on Apple - all that is needed is a bookmark function like you have in books!
