I have quite a few files where there is no compliant cover art, e.g. I want a minimum of 500x500 but all there is is just 300x300, and sometimes there is no cover art at all for a release. That applies, e.g. for a lot of the live concert recordings I have, and prevents me from effectively checking for album art compliance with the rest of my collection. I am aware that I could just upload a placeholder cover art, but that is a lot of manual work, and also that does not help with existing cover art that is too small for my taste.

Bliss should provide a way to mark a release to ignore non compliant cover art. This should be stored with the music, instead of within Bliss itself, and be simple to remove.

A simple way would be to store a custom tag with the file, e.g. BLISSIGNORECOVERART, which then could be grouped within a dedicated category. Also, there should be a way to remove that marker for a release, and maybe even for all releases.

I would not mind if bliss also had a button in the cover art selector that would apply a default image with one click.
