With a week to go until Taylor Swift triggers another seismic quake in the pop landscape, she’s first unleashed her latest tremor. Once again, she has a new song, “Call It What You Want,†which is both a title and a dare. It’s her fourth offering from her impending album Reputation (following “Look What You Made Me Do,†“…Ready for It?â€, and her most recent, “Gorgeousâ€). She teased the song by previewing the lyrics “Holding my breath / Slowly I said, ‘You don’t need to save me … But would you run away with me?’ … ‘Yes,’†which absolutely were not ghostwritten by a fourth grader about their middle-school crush. (We hope.) Reputation, or whatever you care to call it, is out November 10.
