Taylor Swift requires no introduction. She recently became the first artist to win the Grammy for Album of the Year four times. Her Eras Tour, the highest-grossing music tour ever, ends this month. Rolling Stone’s Rob Sheffield, who has been covering Swift since the beginning of her career, is out with a new book on the star, Heartbreak Is the National Anthem: How Taylor Swift Reinvented Pop Music. Sheffield talks with Apple News In Conversation host Shumita Basu about Swift’s gift for storytelling, her expansive fan base, and how she’s empowered a whole new generation of artists.
