Missing Artwork is a macOS application that will find music media in Music.app that does not have artwork. It will also find albums where some files have artwork and some do not. Once these have been identified, the application can fix the artwork in Music.app for you.
When the application is launched, it will read your Music application data, looking for music media with broken artwork. It will then display all the items found. Once an item is selected from the list, it will attempt to load artwork from Apples Music Catalog. Select the image you wish to use for the repair. From the Repair Menu, you can then choose to fix the Partial Artwork or fix No Artwork media, depending upon what you selected. You can also copy the AppleScript code used to do the repair work.
