Dupin Lite is your iTunes duplicates manager.
Dupin Lite handles your duplicate tracks in 3 simple steps:
1. Get Duplicates - gather your duplicate tracks into Dupe Groups based on your choice of criteria. Case-sensitivity/insensitivity and "fuzzy" time matching can identify near-dupes.
2. Filter - automatically designate the single "Keeper" track in each Dupe Group using a variety of versatile filtering options (Most/Least Played, Oldest/Newest Added, Highest/Lowest Bit Rate, and much more) More Info »
3. Purge - remove the "non-Keeper" tracks from iTunes and optionally move their files to the Trash
