A few days ago I had several thousand mp3 files on my iPad 2. This morning when I tried to play my favourite playlist I discovered that only the tracks downloaded from iTunes are on my tablet (not very many tracks). The complete library still shows in iTunes on my desktop - I tried syncing but it didn't restore the files on my iPad. Does anyone know why this would happened and how I can get my music back? I am planning to take my iPad and Bluetooth speaker to Cuba next month and really want my full library.
