Tom got a message from his iPhone 11 Pro that his phone was almost full. So he's been moving stuff off. But how does he back up his playlists? Leo says you can do it wirelessly. Go into settings and look in "about" to see what's taking up all the room. Then, you can go into the Music app and delete the music artist by artist. But in Catalina, you can still sync in the music app as you used to with iTunes. Select Sync check songs only.
