Night and Day is an upbeat, catchy, indie pop track, that starts out with a jazzy electric piano vibe, and progresses to a synth based hook with groovy bass and drums. The vocals are strong and clear, while the backing voices and whispered parts add to its psychedelic feel.
The lyrics, as brought out by the video explore survival in the midst of uncertainty. The protagonist battles their own demons of existential anxiety, while trying to stay afloat in a modern, capitalist world.
