I have a handful of notes about Balance of Power from July 2018 that I'm finally getting around to writing about.
In "Secret Lives," there's a constant shifting between 2nd and 3rd person. The verses have 2nd person pronouns ("I don't know what's on your mind," "You're living secret lives," "I don't wanna stop the things you do," and so on), but the chorus has 3rd person pronouns ("And I wonder where she goes to in the night"). This difference gives a sense of the distinct separation that's a result of the secrecy.
