I inadvertently deleted a Playlist I have on iTunes called "Wishlist," which contained hundreds of songs that I dragged in front the iTMS without purchasing (just the 30 second previews). I kept a backup of my Library XML file, but importing that only restored songs that had been purchased and hence downloaded, and not the links to files within the store. I know that these links are stored "somewhere," and I'd rather than restore the entire HD to the backup. Any ideas on what to copy?
