There’s an existing feature suggestion discussing how to show include tracks where an artist is only the track artist on that artist’s page.
Similarly there’s a suggestion to improve the handling of multiple artists (e.g. where two artists contribute to the same song and that song should show on each artist’s page).
I recommend you comment/vote in those threads in order to avoid distracting votes.
Unless I’ve missed some unique aspect of your suggestion, I’ll close this thread as a duplicate.
