Right now, the options you have for album art are :
- Best
- Art from Roon
- Art from your files
The “best” option means each album will use the highest resolution available cover art available, which could be from Roon’s metadata, from your file tags, or from art that’s stored next to the media files (assuming it’s called front, cover, folder, etc).
There isn’t a way to set preference in the more granular way you’re describing, but feel free to open a feature request and we’ll keep an eye on it. Thanks!
