"Queendom" was composed by minGtion, Anne Judith Stokke Wik,
Moa "Cazzi Opeia" Carlebecker, and Ellen Berg, while the Korean lyrics were written by
Jo Yoon-kyung. In a newspaper interview with
The Post, Wik revealed that the writer's table for the song was four women, and called it "impressive", reasoning that the music industry is male-dominated. She stated that it was written in a "record time" since the song had that "once-in-a-lifetime flow to it". The whole session of writing and recording the song was finished for four-and-a-half hours with some post-production, with Wik adding that writing and recording of the track "happened really fast" and came out "so good". In an interview made by
Vogue with Red Velvet, Wendy revealed that the group had put a lot of thought towards "expressing and showcasing" differently their "unique colors". The group had come up with an idea of storytelling three different concepts which were, "homecoming", "journey", and "carnival", while stating that listening to their song would bring their feeling of "bright and positive energy". Musically, "Queendom" was characterized as a
dance-pop song. JT Early of
Beats Per Minute described the song as house-influenced, noting the "bright piano" and "euphoric synthy", bass-led chorus. Verónica Bastardo of
The Quietus noted the dynamic piano synths chords, "easy-to-remember" hooks, electronic instrumentals, "glimmering" metals and airy synths. Additionally, Bastardo mentioned the big emphasis on rap sections and vocals that fall in between singing, speaking, and "actually" rapping. Kim Na-yeon of
Single List acknowledged the rhythmical combination of flute and brass riffs on a "colorful" synth base, adding to the fun of listening to "addictive hooks", with "bright and colorful" vocals from Red Velvet. Tamar Herman of
South China Morning Post recognized the "lusher synth styling" on which it balanced a "catchy, magical spell-like" chorus, "That's our queendom yeah/Ladida-do Ba-badida). It is composed in the
key of
F major, with a
tempo of 120 beats per minute. Lyrically, the song conveys a message of positivity, highlighting that everyone's "unique differences" is what makes the world "so beautiful". It renders "feminist-centric" message, while also focusing on the co-existence of sisterhood and individuality. Kim Sung-yeop of
IZM noted the song for thoroughly focusing on the message and sensibility, giving an example of the lyrics, "Shall we start again", as it contains an autobiographical story of moving towards a new beginning of Red Velvet. Moreover, Kim described the lyrics, "Ladida-do Ba-badida", as a track that does not "create synergy with the ambiguous concept song" and refuses to offset the plain impression of the overall melody. == Critical reception ==
