I'd like to imagine this is the singing of a broken machine, abandoned in the rouble of a post apocalyptic world, singing this over and over till his creator comes back for him, to repair him, and treat him like his son. Or maybe the robot wonders the wastes and finds a small child, and as they cry after loosing their parents, the machine sings them this melody, and they wander the ruins together, acting as the parental figures to them he never got
