I recently ran into a big problem where I had to completely erase every ID3 tag in my library to restore aobut 5% of my library (confusing, I know). This was no big deal because my iTunes XML file contained all song information. Everytime I click a song to play it, my custom iTunes song tags for that song are replaced with the "updated" ID3 tags. I am losing all of my song information each and every time I play a different song in iTunes. I've already tried deleting all songs in my library and re-importing using my backed-up XML file, but to no avail. The songs are imported with their correct custom tags, but they change when I go to play the song. Any help would be GREATLY appreciated. Extra info: Using a Windows box with the latest version of iTunes.
