Most of the duplicates seem to be gone except in the case of Guns N’ Roses. Here they stubbornly remain. PA 3.5
This is most likely due to the inconsistent apostrophe characters in the track titles.
The track titles for Greatest Hits are using the preferred apostrophe character so if you fix the others that should clear up the duplicates.

Damn, I didn’t notice that. Stupid smart apostrophes
