So if I hit the + sign on any of the For You stuff Apple presents, will it 1) save the playlist locally, 2) add all the tracks to My Music library, 3) if added to My Music how can I delete the playlist and all associated tracks?
Yes it'll add the tracks to your music, it won't save any of the files locally, click the 3 dots next to the playlist name and it'll have an option to remove from My Music
