After using the built-in Smartlist for "Possible Duplicates", I found I still had some dupes because of variations in either Artist or Album tags.
(i.e.: "Best of The Doors", "The Best of The Doors", "Best of Doors", "The Best of Doors" type of variations)
In an effort to locate these as well I made additional "Dupe-Finder" Smartlists which searched for files with matching
1- Artist, Track #, Name
(When sorted, allows for dupes with variation in [Album Name] to be easily spotted)
2- Album, Track #, Name
(When sorted, allows for dupes with variation in [Artist Name] to be easily found)
