For each selected track whose Song Name starts with a number (0-999) the script will copy the number to the track's track number tag. Use carefully; be sure the number is not part of the actual Song title, eg: "12th Street Rag", "5:15", "99 Red Baloons", etc.
This script also used to remove the track number text from the Song Name, but no longer does so. If that is necessary then use Remove n Characters From Front
