The album's lead single "Space Song" is a track about trying to come to terms with mortality, losing people to sudden human fragility and ways we get through this. The song itself came out as a sort of comfort zone, a watery drift to melt into when things are hardest. The beauty of the carbon cycle is we always drink those who came and went before, and some (possibly strange individuals) find comfort in this, that nothing is permanently lost, instead transformed for another cycle.
