I transfered my library from my Mac to my PC and this involved 60+ gigs of music. Well, about 10 GB of music appeared to have completely lost their ID3 tags. They were put into the Unknown Artist\Unknown Album folder when iTunes automatically organized my library. The problem is, when I navigate to this folder, Windows sees the ID3 tags of every single track there. All the music is perfectly in order, with all the correct ID3 tags. But iTunes won't bother reading them. I even started a new library and imported JUST that folder and iTunes still wouldn't budge. How do I get these 10 GBs of music to show the correct ID3 tags in iTunes??
