Description of the issue
The picture contains 3 members from the original Marillion lineup.
One is Mick Pointer, who left after the first album and the second is of Fish who left after 4 albums
Marillion has gone on to release 18 albums with their 19th releasing early next year
This is where Roon’s metadata editing features come in handy. There’s no one “correct” image for bands, artists, performers, composers, etc. It’s going to be a matter of taste. And for some folks the “Fish era” is going to be the preferred Marillion image.
As @Uwe_Albrecht stated, you can take matters into your own hands and choose any image you prefer for Marillion.
Here’s how you do it:
Go to Marillion’s artist page and click the ellipsis button
Click edit
Find the Photo section
Click add image
Find the preferred image on your computer
Click Save
Your preferred Marillion image is now set as the artist image!
