Fall Out Boy has 2 Chainz on the remix single 'My Songs Know What You Did In The Dark.' 2 Chainz joined Fall out Boy during their performance at the 2013 NBA All Star game to perform the unheard verse, now we have the official audio track for you. 

The group Fall Out Boy is known for making majors with known lyrical assassins. Case in point -- Arms Race Remix featured Kanye West, Lil Wayne, Tyga (17yo) & Lupe Fiasco. Murder was the case, early and this song is no exception.
