Missing artist's artwork in iTunes I last iTunes Apple have changed algorithm of displaying picture for Artist. How does it works? Why almost all my Artist's doesn't have artwork?



As I see Alice Cooper have the image:



But why I can't see it in my list?

Update: As I see I can not perform "Show in Apple Music" for this artists. Can it be related with that fact that I have created my own album (Collection) for this artist?
For me it shows only artwork for .m4a files. All the artist I have in mp3 format doesn't show artwork image.
