'Your Cheatin' Heart' -- Hank Williams (1953)

Wandering Words: "Your cheatin' heart will tell on you."

Williams supposedly wrote this song in his car, while complaining to his fiancée, Billie Jean, about his first wife, Audrey. After mentioning Audrey's "cheating heart," he dictated the lyrics to Billie Jean, who scribbled away in the passenger's seat.
