Follow up with an example on why using ToadKing script vs. cover art:
”Down IV, Pt. I - The Purple - EP” álbum de Down en Apple Music, ToadKing script says barcode is 016861762704. Harmony is reporting it as 16861762728, which is what is found in the cover art .jpg filename. So, it won’t let me update Release Actions – Harmony.
Are you sure that the ToadKing script is actually using the Apple Music API? I’d be surprised as it’s not a public API. I can see all this information by using “inspect” on the Apple Music page. Listening to the network on inspect, it says the upc is 016861762704, not 16861762728.
Update: The iTunes Collection match file (iTunes UPC Database) and it also shows barcode of 016861762704. So, definitely not what the .jpg file shows.
