Taylor Swift’s Reputation era has been a rollercoaster ride. On the one hand, it sold a whopping 1.2 million copies in its first week. On the other, it received mixed reviews and hasn’t really made a dent on pop culture. At least, in comparison to the all-conquering 1989 era. Part of the problem has been curious single choices. “Look What You Made Me Do” was something the 28-year-old needed to get off her chest (and provided her with the perfect vehicle for a shady video), but it is a non-song.
