Caren’s rules of hit songwriting: “First, it starts with an expression of ‘Hey,’ ‘Oops,’ ‘Excuse me,’” he begins. “Second is a personal statement: ‘I’m a hustler, baby,’ ‘I wanna love you,’ ‘I need you tonight.’ Third is telling you what to do: ‘Put your hands up,’ ‘Give me all your love,’ ‘Jump.’ Fourth is asking a question: ‘Will you love me tomorrow,’ ‘Where have you been all my life,’ ‘Will the real Slim Shady please stand up.’” He takes a deep breath, and rattles off another four rules. “Five is logic,” he says, “which could be counting, or could be spelling or phonetics: ‘1-2-3-4, let the bodies hit the floor,’ or ‘Ca-li-fornia is comp-li-cated,’ those kind of things. Six would be catchphrases that roll off the tip of your tongue because you know them: ‘Never say never,’ ‘Rain on my parade.’ Seven would be what we call stutter, like, ‘D-d-don’t stop the beat,’ but it could also be repetition: ‘Will the real Slim Shady please stand up, please stand up, please stand up.’ Eight is going back to logic again, like hot or cold, heaven or hell, head to toe, all those kind of things.” The rest is silence.
