To do this, please open iTunes and follow the instructions below:
Finding duplicates via iTunes:
You can find every instance of a song by the same artist anywhere in your iTunes library. For example, the same song could appear on the artist’s album and on a movie soundtrack.
You can also search for exact duplicates, in which the song, artist, album, and version are all the same (if, for example, you inadvertently imported the song twice).
Select an item and do one of the following:
- Find every instance of a song by the same artist from any album in your library: Choose View > Show Duplicate Items.
- Find exact duplicates: Press the Option key and choose View > Show Exact Duplicate Items.
To see all items again, click Show All at the bottom of the iTunes window.
