Are you thinking "Show Album" would be a preference that when enabled always shows the entire album (with one or more tracks matching the filter)
Yes, I am thinking that when a user choses the view-perspective "show album", then that is a view-preference that differs from other views, and which has impacts on how the results are presented.
My suggestion is that non-matched songs for that album can be shown in italics (so as to preserve visual impact for missing tracks, which might be shown grayed-out).
....or do you mean you right click a track from a particular album and it displays all tracks from that specific album?
No, that sounds tedious and a bit roundabout.
And I shouldn't have to specifically chose to show all tracks for an album, when I have chosen the "Album"-view.
If I had chosen the "Tracks"-view, then sure, that's fine and we wouldn't be having this discussion.
But I've chosen the album view, and I'm searching for an artist, and I'd like to see the other songs for CDs which this artist has participated in.
Maybe I can just look them up and see if they are familiar artists?
