[28][24] Album closer "Shooting Star" uses the titular phenomenon as a metaphor for destructive relationships, with "spacey synthesisers and underlying pulsating percussion that builds to coming-of-age-movie prog-rock guitar".

[30] The Line of Best Fit critic David Cobbald gave the album a perfect score, saying "MUNA is all killer no filler.

[25] David Roskin of Gigwise praised the release, saying "With a collection of bangers, slow tunes and refreshing melodies, MUNA are magic.
