Q: Somehow I've ended up with many exact duplicate songs in my ITunes library. How to delete them without losing both songs?

Hi skugler99,

I understand that you have multiple duplicates within your iTunes library that you would like to delete. That is something I can help you out with.

You do have the option in iTunes to view just the duplicates and the exact ones from the same albums. Then it would be a matter of choosing which one you want to delete. Take a look at the article below for more details.
