On Thursday, Taylor Swift went public with the latest tensions between her and Scooter Braun and Scott Borchetta, the music executives currently in control of her back catalog. It was an attempt to wrest control of a situation that’s unfolded in ways unfriendly to her. What she can control, however, is what she releases moving forward; two new songs came this week. “Beautiful Ghosts” — written by Swift with Andrew Lloyd Webber, for the forthcoming “Cats” film adaptation — is successful, by the terms of the “Cats” ecosystem. Swift sings melodramatically, and with an indeterminate accent, but isn’t over the top in the way Webber is best suited. Something similar happens on the remix of “Lover,” from her album of the same name, which imports Shawn Mendes as a tool of extending its life to little effect. Mendes is at his best when he’s jangly and punchy, but this song is too tightly wrapped, too pristine, for him to triumph over. He’s a rowdy cat, and Swift is content to simply purr. CARAMANICA
