1. Edit the tracklist to change most track names to something else. In my case changing from the old tracklist to http://www.sonymusic.co.jp/Music/International/Arch/SR/Jay/SICP-1004/
2. Go to Recordings and spend 10 minutes searching for and matching the correct recordings
3. Find a typo in one of the track names
4. Go back to Tracklist and fix the typo
5. Go back to Recordings and find that all your work is lost!
