iTunes album artwork incorrect on 2019 MacBook Pro
I have a MBP 16-inch 2019, 2.6 GHz 6-Core i7, with Apple iTunes v1.5.6.11. I also have another 2024 MBP M4 running the same version of iTunes. I was listening to music on the 2019 MBP, and all of the album artwork was correct. All I had been doing on this MBP was listening to music so it went to the screen saver. About an hour later I needed to turn it off, so I typed in my password and a small portion of my album artwork were incorrect. For example, one band's artwork had the "words of what the images were"... e.g.: Pink Floyd's Animals cover was a black box with the words, "A Pig Floats Above Battersae Power Station". Same for the rest of my Floyd albums. Some of my Metallica albums randomly defaulted to the "Black" album cover, but not all (some were correct).
All of the album artwork on my 2024 MBP is fine.
I tried getting album artwork but that did nothing.
I then tried signing out, closing the program and deleting the following cache: "com.apple.iTunes" and "com.apple.Music", restarting, and signing back in, but nothing changed.
I've done a search for this, and I've seen a few items related to iPhone artwork, but those solutions are related to the iPhone.
