Dog Years is a “heart-shaped box”-esque slowburner. Its lyrics steam with hate. Dog Years reveals the vitriolic aftermath of a relationship. In its soul-crushing relentlessness, the song captures how the subject of the song meticulously ruined life’s simple joys. Jenna Moynihan begins by singing, “If you could do anything / You would ruin the best things / You would spoil the ending / You’d dissolve cotton candy.” Later on she seems to find sadistic pleasure from imagining the death of whomever she is singing about. The pain and disgust are palpable.
