I was on iTunes with my iPod disconnected and I was editing song artists, deleting songs, editing albums and etc. I then plugged my iPod in and it said it was syncing. I waited and it was done. but nothing updated on my iPod. The artists were still the same, the deleted songs were still there, and everything else was the same. How do I update my new Library Music Folder with my iPod? Everything is changed on iTunes, I just need it changed on the iPod.
