http://caa.mbsandbox.org/release/36ad0bd7-a46f-4335-ae28-aadb3702a4f3/cover-art has cover art from a cover art relationship. Despite that, the cover art tab says "We do not currently have any cover art for SPIRAL." I understand that the cover art tab is only for cover art in the cover art archive, but other people less familiar with MB will find it confusing that we're showing cover art yet claiming we don't have any cover art. I think the most logical option would be to replace the "We do not currently have any cover art for ..." message with a message along the lines of "The only cover art for this release is provided by relationships" when that's the case.
