At first most of my music library had red rings around squares next to songs, after researching one of the fixes was to do a sync on the computer, I did this but now they have all just gone. I have the songs that originally didn't have a symbol but ones that had a symbol are gone, how can I get them back? Or anything! I was listening to the songs that have gone just yesterday!! Quite annoyed! I started with 1007 songs and now have 311!
Also, when I plugged my ipod into a computer the songs that had a symbol on my ipod had an explanation mark next to them in itunes (11.1) ipod runs latest version of ios 7
