Hi, I had an iPhone 4, and all my music synced fine. Yesterday, I got the iPhone 4S, restored from my iPhone 4 backup and synced all my music. However, I noticed my song count was about 300 songs short. Eventually, I figured out it wasn't syncing the songs I bought on iTunes back in the day when they we're rights protected. On the iPhone, I can go to iTunes->Purchased and see all these songs and download them to the device, but my iTunes on my mac has always managed them, why can it no longer? I just want all my music to sync over. It's like I need to 'authorize' my 4S to play my purchased music, but I see no way of doing that. Please help.
