iTunes only mounts MP3 CDs made in iTunes. This script will create a playlist of all the MP3s on an MP3 disc made by another app (like Toast) in iTunes. (OS9 only - some of the OS 9 Finder commands which this script uses no longer work in X).
OBLIGATORY WARNING! Because this script has been designated as a "Retro Script" there is no guarantee that it will function as described and may even corrupt or destroy data.
