Find duplicates
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).
Note: You can find duplicates for songs, movies, TV shows, and audiobooks.
Go to the iTunes app
on your PC.Choose an option (Music or Movies, for example) from the pop-up menu at the top left, then click Library.
If you don’t see Music, Movies, or TV Shows in the pop-up menu, you need to use the Apple Music app
or the Apple TV app 
you installed on your device. See the Apple Music User Guide for Windows or the Apple TV User Guide for Windows for more details.Select an item, then do one of the following:
Find every instance of that item in your library: Choose File > Library > Show Duplicate Items.
Find exact duplicates: Press and hold the Shift key, then choose File > Library > Show Exact Duplicate Items.
After you find duplicate items, you can delete them if you want to declutter your library.
To see all items again, click Done in the top-right corner or choose File > Library > Show All Items.
