This script can be used two ways:
When run as an Applet, it will use the assigned artwork from the selected tracks as the icon for the folder containing each track's corresponding file in the Finder--presumably, this is the file's "Album" folder.
When launched as a Droplet--by dragging one or more folders to its icon--it will examine every folder (at all depths) for the first audio file in any folder that contains image metadata and use that image as the icon for that folder.
