Didn't know your childhood would someday drag you down The heart is a muscle, you got a strong one now So proud when you stood up for the ones they put down The heart is a muscle, you got a strong one now You were born with a heart That learned how to come apart It was young back then Time never was a friend Didn't get all the love A child needs growing up That's a hell of a thing Try and fly with a broken wing Seven billion souls, you're the one that I found The heart is a muscle, you got a strong one now You just keep on shining through a dusky, gray cloud The heart is a muscle, you got a strong one now You were born with a heart That learned how to come apart It was young back then Time never was a friend Didn't get all the love A child needs growing up That's a hell of a thing Try and fly with a broken wing Yeah you were born with a heart That learned how to come apart It was young back then Time never was a friend Didn't get all the love Someone needs growing up That's a hell of a thing Try and fly with a broken wing You carry your love for us, devoted and bound The heart is a muscle, you got a strong one now The heart is a muscle, you got a strong one now
