Open the Music library in iTunes. Press the Alt key(Windows 7 & 8),Shift key (Earlier versions of Windows) or the Option key (Mac) and click the View menu. Select 'Display Exact Duplicate Items'. This will change your list of songs to all of the duplicate tracks on your computer. These are duplicates that share the same song name, artist, and album.

2. Make sure you are using the [Update-iTunes|latest version of iTunes]].
3. Older versions of iTunes may have the 'Display Exact Duplicates' option in the File menu instead of the View menu.
