So I just made the switch over to the new iMac. I transferred all my files from my PC to an external HD, and then transferred them to the Mac. Now, only some of the songs will play on my iPhone. All the music works fine in iTunes, but most of the songs won't play at all on my iPhone...most of the time, the screen will show that they are playing, but there's no music. Before you ask, yes, I have the volume turned up. I thought it may be a DRM issue, but the songs are a combination of songs that I downloaded from iTunes on the PC and songs that I burned from CD's. Anyone faced a similar issue? I was going to just restore my iPhone through iTunes, but before I went there, I wanted to know if anyone knew an answer. Thanks!
