I know there are other threads about this issue, but mine is different. My artwork does show up on the iPod, but if I were to update the artwork on my iTunes, and sync my iPod, the new updated artwork will not show up on my iPod. Only the old artwork will show. I have not or never jailbroken my iPod. The only thing I have done to my iPod was change the bit rate from its original size to 128 kbps AAC. That may be the problem, but I do not understand. My iPod is up to date in all its apps and software (iOS 6.1.3), as well as my 2012 MacBook Pro (10.7.5). It would be much appreciated if someone will explain my problem to me. Thanks in advance!
