ITLU is a utility that adds, deletes, and updates the headers of files in iTunes library for files in a directory structure outside of the iTunes Music folders.

Anyone know if this utility is compatible with iTunes 9?
(I understand that a new "Automatically Add to iTunes" folder in iTunes9. However, this does not delete or update the mp3 header information if the headers are deleted or edited outside of iTunes, using software like MP3Tag. Also, the files added must reside in the iTunes Music folder. I keep my music on a separate external USB drive.
So, for many reasons, ITLU is still a useful utility, if it still works with iTunes 9).
