"Heirloom" alters "between what sounds like a samba preset on a vintage Wurlitzer organ and skittering breakbeats, and is decorated with inverted synthtones and analog keyboards". The song's lyrics tell a "fuzzy story" about a recurring dream, while "the art of singing to swallowing and exhaling 'glowing lights'" as Björk sings: "During the night/They do a trapeze walk/Until they're in the sky/Right above my bed". Film director Harmony Korine wrote "Harm of Will"'s lyrics. The "Slate" album review noted the minimalist nature of the track, pointing out a lack of hook, beat and melody. It is a slow song, as is the closing track, "Unison". The latter "[contains a refrain directly inspired by [Björk's] experience in "Dancer in the Dark" and a healthy dollop of self-effacing humor evoked to counter the balance". It "brings beats and strings together in a final crescendo that also manages to incorporate a little jungle".
