Taylor Swift’s conversion from country superstar to a full-blown pop idol was complete by “1989,” which yielded three #1 singles and sold more than 1 million copies in its first week. Named for the year Swift was born, the album finds her once again in an autobiographical mood as she dishes on her relationships against a synth-heavy, ‘80s-inspired backdrop. Swift claimed the films of John Hughes served as a major influence while she was making the album.
