The biggest song of the last few months is easily 'Gangnam Style' by Psy. Now, he is getting mashed up with one of the biggest movie theme songs of all time.

Yes, this one will be in your song all day. It's perfect when you think about it. The Halloween season is here, and Psy is kind of always in costume - a fancy costume if we don't say so. Could this be the next big move for Psy?

Let's hope more of these mashups keep coming,because it keeps us dancing!
