The Endlessly album has the theme of love. Duffy told The Sun newspaper: "The topic of love doesn't have to be sexual or about a love relationship - it can just be about the way people interact." She added: "Breathe Away is about regrets of being foolish and young."
Kacey Musgraves originally offered "Follow Your Arrow" to her friend Katy Perry. However, Perry thought Musgraves should record the song herself as it seemed, "like something that you would totally say."
