I believe if you go to the Composers tab, tap the icon at the far right of the filters bar that looks like a circle around a downward arrow (to view the additional filters), you can set the composers filter to "Unassigned". Then only composers with no songs will be shown. You can enable Settings->Library Settings->Show Number of Songs to verify that each one has 0 songs in it. You can perform these same steps with the other group types.
