Losing your Apple Music playlists can be a frustrating experience, especially if they contain songs that are important to you. Fortunately, there are a few different ways to get them back.
One way to get back your Apple Music playlists is to check your iCloud Music Library. If you have iCloud Music Library turned on, your playlists will be backed up to iCloud and you can restore them from there. To check if iCloud Music Library is turned on, open the Settings app on your iPhone or iPad and tap on Music. Then, tap on the iCloud Music Library toggle switch to turn it on.
