I assume you are using the version of shs and module script.module.metadatautils from Marcel Repo .....
He didnt bump the latest changes as new version.You don't have code for this Art, you use old code.Author of your skin and me we owerwrite that part, we have ClearArt.
Last update was Sep 21 (version 1.0.17)....changes for adding ClearArt was 16.11. , your version dont have ClearArt for Music.
right?

You need to manually copy all code from this page.
https://raw.githubusercontent.com/marcel...audiodb.py
and paste with editor in
c: \ Users \ ##### \ AppData \ Roaming \ Codes \ addons \ script.module.metadatautils \ lib \ helpers \ theaudiodb.py

Thank you for looking into it. It worked. Great.
