I would prefer it that a highlighting rule gets matched (and the related icon gets displayed) when any track of an album matches that rule.
Currently it only looks at the first track of an album.
I have an indicator for when an album contains tracks that have no ReplayGain calculated.
It fails to indicate that when none of the tracks have ReplayGain values except for the first track.
I have an indicator for compilation albums. When tracks for an album have a tag value for 'Original album', I have an icon for 'Compilation' that I would like to have displayed.
But that will also fail when the first track doesn't have that tag populated, even if all the other tracks do have it.
