Almost everyone who uses iTunes has duplicate music tracks in their iTunes library. Finding them, and figuring out which ones to keep, can be a cumbersome chore.
Dupin, from Doug’s Apps for iTunes, can search your music library or playlists for duplicate tracks. You set the criteria for what constitutes a duplicate. When Dupin finds duplicates, it will keep or delete them, based on criteria you select in its filtering system.
