That’s not up to you to say. Music is something that’s always changing. There’s no goal posts. Young girls like the Beatles. You gonna tell me they’re not serious? How can you say young girls don’t get it? They’re our future. Our future doctors, lawyers, mothers, presidents, they kind of keep the world going. Teenage-girl fans – they don’t lie. If they like you, they’re there. They don’t act ‘too cool.’ They like you, and they tell you. Which is sick.”
