Some artists have participated in a large number of collaborations, or have been credited as a feat. artist in a large number of releases or recordings - such that their pages are nearly overrun with them.

It would be nice to have an option that limits the display to show releases / release groups / recordings, etc. where the artist in question is the /only/ artist linked to the artist credit.

This serves a similar purpose to the current 'various artists'-excluding display, but is even more restrictive.

(One downside that I can think of is that it will not show entities with a credit "X feat. Y" on X's page: I'm not sure whether this is a good thing or not.)
