Taylor has a mystique about her Track Fives. On any given album, it’s the emotional bloodbath. “All Too Well” is the most famous of all Track Fives, but they never fail. “My Tears Ricochet” on Folklore. “White Horse” on Fearless. “Delicate” on Reputation. “The Archer” on Lover. “Tolerate It” on Evermore. “Dear John” on Speak Now. “So Long, London” on The Tortured Poets Department. “You’re on Your Own, Kid” on Midnights. (“Cold as You” on the debut passes the test, but not the bouncy “All You Had to Do Was Stay” on 1989, which feels more like a track nine.)
