So much for shaking it off. After Taylor Swift's initial foray into "official" pop, 2014's earworm-infested "1989," it seems the haters have triumphed, leading everyone's favorite girl "on the bleachers" to embrace her inner mean girl. At least, that would be the pop psychology take. Many of us in marketing, however, recognize Ms. Swift to be a cunning, calculating positioning savant, and the new, edgy, and angry Taylor is nothing but a brand refresh.
