Moving my kids' music to their account
I'm trying to solve a parent's nightmare - my kids' music is littering my music library.
Our family (me, wife, two kids) have an iCloud Family, with Apple Music through an Apple One membership. We've had Apple Music since launch, but (for historical reasons no longer relevant) share my Apple ID for music and purchases. This was fine when the kids were young and we managed every aspect of their digital lives. They are now teenagers with their own musical...tastes (insert me complaining about "kids these days" as my parents did with me). They add new songs daily, and have created a number of comprehensive playlists. My "Listen now" and other recommendations are heavily biased towards their music. It's time for a musical separation.
I know I can sign them into their own music and purchases accounts, but they'll start from scratch. I'm ok with app purchases - Apple deals with that fine. They have no music purchases (I have plenty from iTunes Store days, not to mention thousands of songs ripped from old CDs - they won't care about any of that).
I've created a playlist of all my Apple Music songs. It appears I can share the playlist with another user. Presumably once I do, my kids can then then add all the songs to their library. I can then do the same with their ~100 custom playlists. I'll then go through my library and delete the songs and playlists. They'll presumably they'll do the same.
Does the above make sense? Or is there another approach to consider?
