When listens have a MBID that match to a specific release it only displays a cover if that specific release has one.

Because we can set a release group cover (yay) we have a lovely image to use for listens for releases without covers as well!

This is quite important because as it is currently it motivates people to clone identical covers across releases in a group, for instance pseudo-releases which shouldn't have a cover. As someone who has added thousands of covers to last.fm over the years I can confirm that this will become a problem if LB continues to grow

It may also be useful to allow users to toggle ( ? ) release group covers for all listens eventually, if they prefer the cleanest possible image? food for thought
