Top Of The World

This feel-good, sentimental offering was written by Josh Osborne, Jimmy Robbins, and Jon Nite. The lyrics describe McGraw's love for his woman as he explains how with the right person by his side, the rest just doesn't matter: Don't know where we're gonna be But I know we're gonna be Sittin' on top of the world So keep hanging on to me McGraw introduced the song by beaming the tune to the astronauts aboard the International Space Station. They responded via Twitter, saying, "You're on #TopOfTheWorld... we orbit around it." It was released to radio on August 4, 2015.
