I have the same problem on 3 devices. A I-Pod Touch 5, an I-Phone 5 & an I-Phone 5S. Originally my music meta data was missing artwork and metadata was "confused" to say the least. A total restore & reinstall on all three devices helped with the music, although I haven't been able to determine if anything is missing yet, with over 5,000 song files to go through. Even after restoring the software the video/movie artwork is still gone from each device. However, It still exists in I-Tunes. After the problems experienced with IO-7 when the device wouldn't finish a sync with I-Tunes, you'd think that Apple would have gotten their act together this time.
