Audio "Artist" artwork metadata issue

[Former user]

The "Artist" art work is sometimes wrong due to inclusion of composer data rather than using the artist/album data.

I have tried it on several control units (BubbleUPnP, Mezzmo and Asset Control) with the same problem so it points to a Serviio issue.

An example is the artist artwork for Al Green showing an album cover by Seal (as there are two tracks composed by Al Green on the Seal album).
