Buried in settings there's a way to turn off Apple Music (the subscription) and limit to only your own mp3s.
I tried to run both my music library and Apple Music subscription together, but found that when I let my subscription lapse, all my playlists got deleted, even the ones that just used my own music. Now I'm staying FAR away from apple music the subscription.
