Why won't iTunes sync my music back onto my iPod touch?
I have always been syncing my iPod touch to iTunes and this morning I went to iTunes and it asked me if I wanted to update iTunes. So I agreed, and then later, it asked me if I wanted to get the 5.0 version on my iPod touch. I agreed also, but then when I tried to put more music on it, iTunes synced it, but nothing happened, A few tries later, I restored my iPod touch and now when I try to get the music synced to my iPod, it doesn't do anything. I added free apps to my iPod and it synced fine. What is the problem?
