iTunes 12.3.1.23 won't download album artwork despite correct metadata
For certain albums, iTunes 12.3.1.23 won't download album artwork despite correct metadata.
It will download other artwork (sometimes even when the metadata doesn't properly match).
Is there any way to determine the metadata that must be used to force iTunes to actually download the art for a specific album from the store?
Or is there any way to download the artwork from the store to an album without changing metadata?
If iTunes works the same as it has for a while, I do not want to download the artwork manually, then manually associate it with the iTunes tracks, because that adds a copy of the artwork to each file. (if iTunes has been changed to not insert a copy of the artwork into all of the track files when manually adding artwork instead of downloading it from the store in iTunes, please let me know)
