Q: I'm not quite sure what has happened.  I can still play my movies, but I cannot play any of my songs in my library.  I cannot even play a preview song in the Itunes store.  Any suggestions as to what has happened ?

I'm not quite sure what has happened here.  I can still play and access my movies in my library, but I cannot play any of my music.  They just won't play.  I cannot even play a preview song in the Itunes store.  Doesn't make sense.   All of a sudden happened
