One of the neatest features in Apple Music is the For You tab. Specifically, the New Music Mix and My Favorites Mix playlists, which update every week with a whole new set of songs. But what if you dig one of these playlists so much that you want to save it? You can’t. Or at least you can’t unless you use an app like Music Launcher, which has a great kinda-hidden feature that saves Apple’s transient playlists in a permanent form.
