Force duality is one of Darth Slipknot's favorite powers to both use and sing. It really is a power that is like a distraction to his enemies. He recorded it at first before he robbed and rampaged a house because he loved his song so much, and like Force Before I Forget, he made it into a single and sold it, of course, you'd meet your end if you refuse to buy it, nice guy, he must be a gentleman.
