Its actually lost. I have no idea how my iTunes library is working, because I cannot find this file. I was trying to set up Corripio (a nice little app that downloads album art from the iTMS for those of us without a credit card and therefore account) and it asked me to locate my iTune Music Library.xml file, since it couldn't find it in the default Music/iTunes folder. I can't find it anywhere! I've changed my iTunes Music folder (the one with all the songs) to a shared folder, but I tried poking around in there to no avail. I even did a Spotlight search and the only .xml files that popped up where the 'iTunes 4 Library' found in the Previous iTunes Librarys folder... I can export a file, which I have done in means of a backup, because I'm wondering just how my iTunes is remembering all my playlists, etc. And yes, I've quit iTunes and restarted and it works normally. Thanks in advance for any help.
