Taylor Swift looks around and sees enemies everywhere on the aggrieved but not triumphant “You Need to Calm Down.” Tsk-tsk is a familiar mode for her, and typically she inhabits it with cheekiness and a raw sense of indignation. But here, her singing is deadpan and heavily filtered and processed, compressing all the joy out of her voice. And the lyrics draw implicit parallels between mean trolls (“Say it in the street, that’s a knockout/But you say it in a tweet, that’s a cop-out”) and actual bigots (“Why are you mad when you could be GLAAD?/Sunshine on the street at the parade/But you would rather be in the Dark Ages”). This is the second song from Swift’s seventh album “Lover,” which she just announced will be released in August. Its groove is slow and deliberate, with shades of electro and dub, and the stacked vocals have a pleasant thickness. But Swift used to win battles with wit and savvy, not weapons of mass production.
