Home News Barack Obama Says Kendrick Lamar’s ‘How Much A Dollar Cost’ Was His... Barack Obama is really coming up on Bill Clinton as the dopest President of US history. In an interview with People Magazine, Obama revealed that Kendrick Lamar‘s ‘How Much A Dollar Cost’ off his illustrious To Pimp A Butterfly album was his favorite song of 2015. Unfortunately, Michelle’s favorite song was Mark Ronson & Bruno Mars‘ ‘Uptown Funk’. Sigh. But shout out to Obama one time.
