There’s a smart duplicate song remover in FixYouriTunes that searches and researches your song library to find all the duplicates. It even finds duplicates that are spelled completely different than the other songs. You can use the options to choose to keep the songs with the highest bitrate or longer length whichever you prefer.

Simulation mode allows you to test things without accidentally removing songs you want to keep.
