removing duplicates from zune software

[Envy]

yes i know this is going to sound really noob but im new
i was wondering is there a program that can delete duplicates of songs :s like itunes has one for example (used to have ipod thats how i know ;p)

I know u cant add the same song 2x but i have alot of songs and some are from the Best of Chilli Peppers and i dont want doubles of there songs ? so ny idea
