Cover art for Runnin' lyrics by Jesse McCartney

I think it's about a boy whose to consumed with not wanting committment to actually committ to this girl. He knows how amazing she is but he just can't settle down. He's too into himself and how much fun he's going to have before he's tied down. And then he finally realizes that she is more than he deserves and wakes up. Unlike some guys.
