UPDATED: Artwork as Album Folder Icon v3.0
For macOS 11 and later only. 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.
Latest version:
- Accommodations for macOS 12 Monterey
