All the grudges Swift sings about in Reputation’s best and pettiest track.

Listening to a Taylor Swift album happens on two levels. There’s the cursory listen, the one that reveals which songs sound completely different than Swift’s past work, which songs have that signature Swift earworm quality, and which songs aren’t quite up to snuff.
