Frustrated trying to manage duplicate tracks and files in iTunes on your Mac?
Of course you are!
iTunes' "Show Duplicates" feature is helpful but you still have to examine every track to determine whether you want to keep or delete the tracks it finds. Smart Playlists are of dubious help and trying to locate all duplicates with them can be tedious as they can quickly crowd your Source list and slow iTunes down.
Now there's Dupin.
Dupin is your iTunes duplicates manager.
