Can't delete downloaded artwork in Apple Music
A recent update of Apple Music lost most of my album artwork. I decided to select all albums and "Get Album Artwork", but this seems to be quite buggy, and downloaded many incorrect images. For example, I have a few trance albums that ended up with Giuseppe Verde on the cover, which I find extremely annoying. Apple also doesn't seem to have quite a few mainstream album covers.
Fine, I decided to delete the incorrect ones, so I selected "Clear Downloaded Artwork". It appears to remove the artwork from the album, but when I restart Music, there is it again. No amount of retrying fixes the issue. I've had to restore from a backup to wipe all the downloaded artwork.
I'm using Music version 1.2.5.7.
