In a new interview with People Magazine, President Obama revealed that his favorite song of 2015 was Kendrick Lamar’s To Pimp A Butterfly cut, “How Much a Dollar Cost?” (The FLOTUS was on hand as well, with her pick going to Bruno Mars‘ “Uptown Funk.”) Pretty cool! Shortly after the interview was published, TMZ cameras caught up with K.dot as he was running through LAX, and got his reaction to the exciting news. He’s not a man of many words.
