Today I decided to sync my entire iTunes music library to my 32GB iPhone 3GS. After the sync was complete, I noticed that several albums are missing their artwork. It seems completely random as to which ones are missing it. I know for a fact that every album/song I have in iTunes has album artwork. The artwork is embedded in the actual files, not simply stored in some other folder like the way iTunes retrieves album artwork. I have tried re-syncing several times, but the same albums are missing artwork. Does anyone else have this problem? Any solutions?
