"Go Away" is described as consisting of wavy, synth-filled instrumental and nostalgic sentimentality with hypnotic and washed-out guitars alongside vocal layering and punchy alt-pop percussion.

Jon Blistein of Rolling Stone wrote that it has "slick groove and [is] fleshed out with gauzy synths and stray guitar lines".

"[5] Thomas Bleach described it as a "smooth and captivating RNB-pop track", continuing, "It has a freeing and authentic energy embedded into the production that still feels organic and warm.

"[6] Liv Rose from Gig Goer stated, "It's a funky bedroom soul jam with striking high notes and dreamily exquisite harmonies, Go Away stuns with its unfiltered, romantic lyricism.

"[7] A music video to accompany the release of the song was first distributed on YouTube on July 8, directed by Jenna Marsh.
