Sony Pictures has released the official theme song for Men in Black III, which is set to hit theaters May 25. Unlike Men In Black and Men In Black II, which featured theme songs from franchise star Will Smith, Men in Black III's theme song Back in Time comes from Pitbull, which touches on the time-travelling themes in director Barry Sonnenfeld's 3D sequel. Check out Pitbull's Back in Time.
