I want to display, for example, all the songs that are not included in any albums. So I search by Album...but what do I put in the search field?

Wait, figured it out via RTFM. Hit the "additional filters" button, select Albums, and either set the Mode to Unassigned or select specific album(s) & set the Mode to Exclude. Magic.

I do have a lot of extra filters in that popup. When I rework the filters and have them all in a side panel, I think users will find that easier to access, as it will be less hidden.
