How to automatically delete duplicate songs in Apple Music

There's Find duplicate items in Music on Mac - Apple Support

but I don't know that I would implicitly trust anything to make the deciding call on if something was a duplicate. Check to make sure something reported as a duplicate truly is because I have had tracks that were very similar but were not duplicates.
