You can search for items that have the same title and are by the same artist.
To find duplicates:
Select an item below Library or Playlists, and then do one of the following:
Choose FileÂ > ShowÂ Duplicates to find every instance of a song from the same artist from any album in your collection. For example, the same song could appear on the artist’s album and on a movie soundtrack.
Press the Shift key and choose FileÂ > Show Exact Duplicates to find multiple copies of the same song (if, for example, you inadvertently imported the song twice).
To see all items again, click Show All at the bottom of the iTunes window.
