Itunes and duplicates...

I assume you have made sure you were in your Music library and gone to Edit > Show duplicates and then manually deleted all duplicates (being careful to make sure the file you are leaving is a working file). Deleting your playlists will not get rid of duplicate songs.


Have you tried to delete all songs from your iTunes library (NOT your hard drive) and add them back? (this is assuming you do not have the duplicates on your HD also.)

(If you wish to try this, please back up your songs on an external drive just in case.)


To remove all songs:

To do this Edit > Select All > Delete

When it asks if you are sure you want to remove the selected song from your iTunes Library, click Remove

When it asks you if you want to move it to the Trash or keep it in the iTunes folder, click Keep Files.

Make sure that under Edit > Preferences > Advanced the "Copy Files to iTunes Music Folder When Adding to Library" option is unchecked

Then under File click on Add Folder to Library and navigate to your music folder. Click OK to add them back.


When done, go back and recheck Copy Files to iTunes Music Folder When Adding to Library and also make sure you have the Keep iTunes music folder organized option checked.
