I noticed that iTunes "dropped" one of my favorite songs ... it just disappeared from the library. (It's possible I deleted it by accident, but I doubt that ... it's one of my favorite songs, after all!) I had another copy of the song elsewhere on my hard drive, so I tried to use the "Import" feature to bring it in. However, it doesn't add the song to the library, and doesn't give me any sort of error message. I've tried opening and closing iTunes, restarts, repair permissions, etc ... no luck. Ideas?
