As a CIA agent on a top-secret mission, Duff Dixon traveled through time using a device given to mankind by inter-dimensional aliens. After ten billion long years of trying to save the world, he's ready to enjoy his retirement. On Play it by Year, Duff explores the history of popular music with a twist: each episode focuses on a single year and the songs that defined it. So tune in as Duff talks pop, rock, hip-hop, jazz, country, life, Texas 5A division 2 high school football, and (at the insistance of his pushy callers) the future, aliens, and the CIA's deepest, darkest secrets.
