To automatically delete duplicate songs from your iTunes library, follow these steps:
iTunes also provides a way to find and get rid of duplicate music. However, what if you have 4 or 5 duplicates of the same song, from different sources e.g. original, live version, extended version, radio edit etc. Or what if you have complete albums which have been duplicated?
If you have a lot of music duplicates, it could take hours of analysing and listening to each track to decide with track to keep and which to delete. This is where Tune Sweeper could save your valuable time (and sanity…).
Tune Sweeper provides the ability to select all duplicates to remove, and which to keep, in just a click of your mouse. You can chose to keep the tracks of Highest Quality, Longest Duration, Latest Added, Oldest Added or Latest Played.
Another advantage is that you can specify search criteria for Tune Sweeper to return strict duplicates (an exact file copy), or all tracks with a matching title. You can return a detailed search for duplicates by:
Removing Duplicates is not the only thing Tune Sweeper can do though… The program will also allow you to fix missing or incorrect track information on your music, download album artwork, and clean up your iTunes listings by removing missing music, or adding music from your hard drive which is not yet in iTunes.Find out more
Once you’ve launched iTunes and your music library is displayed, you’ll need to display it by songs. To do this, click the Songs header in the menu bar on the left of iTunes.
You can download the latest version of iTunes from Apple's website.
Now, you’ll be able to find your duplicate songs. In the menu bar at the top of iTunes, go to File -> Library -> Show Duplicate Items. This option will display only duplicate tracks from your current iTunes library. If the duplicate pairs are not grouped together, you can click the Name column header to group them.
From here, you can simply click a track, or hold down the ctrl key while clicking multiple tracks to select them. Once you have made your selection, go to Song -> Delete to delete your selected music.
