I am very unhappy. My two main playlists, with over 500 carefully picked songs between them, disappeared today. The playlists were not on my iPod, but they were on my MacBook. I synced the iPod so I would have them on the device, and they promptly disappeared from both devices. What is going on? Please help. Thank you.
MacBook Air, OS X El Capitan (10.11.3), The MacBook is 3 years old.
