Then why hasn't she? This is a question that hasn't been answered by Katy stan. Katy has hits, promo and radio play, yet she hasn't outsold Bey. She's playing catch up tbh. Bey hasn't promoted since the Grammy's, so that gave Katy plenty of time to catch up by now, but she hasn't.
At this point, Artpop will catch up to Prism, before Prism catches up to Beyoncé. If it ever does.
