About iDupe
iTunes has a “Show Duplicates” command, but it is of limited use. It offers no way to remove duplicates while keeping one version of a song. It can’t identify which songs are duplicates as opposed to different recordings of the same song.

iDupe deals with this in a smart way. Playlist entries which refer to exactly the same file and “dead tracks” are treated as unambiguously undesirable. Other potential duplicates are ranked according to a number of criteria, which include whether a song is likely to be a loose single, what the best bit rate is, etc.
