What Dierks Bentley song did Obama quote in his speech?

I heard them talking about it on the radio, but they never said what he quoted, or the song title.|||"Dierks Bentley called Country music the best shrink that 15 bucks can buy", the President stated. Pres. Obama also revealed he is a closet Country fan, telling the assembled crowd, "A lot of people think I'm a city boy, but I do appreciate listening to Country music...Country contributed to the life of this nation and chronicled the history of our people."
