• Here, Lady A pay tribute to the effect a song can have on a listener when it enters into their heart.
  
  It can make you dance and make you cry
  Make you wanna give it one more try
  Start a band, and kiss that girl
  And break some rules
  It'll make you give your heart and get it back
  Change your mind just like that
• Ryan Hurd co-wrote the lyrics alongside Lady A's Charles Kelley, Sam Ellis and Laura Veltz. "That was the first time I co-wrote with Charles, and he's been a good friend and a good mentor to me," Hurd told Billboard. "It was a song about songs, without doing that thing where it mentions actual songs. I thought it was a creative way to approach it."
