2023 was a busy year for K-pop. As the South Korean industry moves at lightning speed, new albums were released almost every day, and dozens of artists made their debuts. K-pop tours crossed the globe, and acts like TWICE and BLACKPINK filled out stadiums. Songs like Jung Kook’s "Seven" featuring Latto, or Fifty Fifty’s "Cupid," were playing everywhere, from TikTok to Target stores.
Amidst so much content, what singles best defined this year? There’s mighty chart-toppers, such as NewJeans’s "Super Shy" and AKMU’s "Love Lee," and sales monsters like Seventeen’s "Super" and Jisoo’s "Flower." Of equal importance, there are also songs that entered our collective unconscious — whether for their flawless melodies, such as NCT DOJAEJUNG’s "Perfume", or for their sassy irreverence, like (G)I-dle’s "Queencard".
In terms of musical trends, retro sounds dominated the scene, taking inspiration from synth-pop, to disco, to Jersey club. There’s a few blustering tracks, too, proving K-pop’s versatility and reinvention powers in a style that has been often overused.
Years from now, when we look back to the sounds that shaped 2023, the 15 songs below — listed by order of release — will definitely be remembered:
Fifty Fifty - "Cupid"
Rookie girl group Fifty Fifty turned heads with their sublime debut EP, The Fifty, at the end of 2022. This year, they made their first comeback in February with the sweet "Cupid" and reached even further. The single went massively viral on TikTok, peaked at number 17 on Billboard’s Hot 100 chart, and reached no. 8 on the UK Singles Chart.
Fifty Fifty were poised to be 2023’s big breakouts — an impressive feat for a group coming from a small company like ATTRAKT. However, at the end of June, the quartet found themselves embroiled in a complex legal battle against the label. In October, ATTRAKT terminated the contracts of members Aran, Sio, and Saena, leaving Keena as the only active member of the group. For all those reasons, "Cupid" is a bittersweet listen. Its sugary synths and bubbly harmonies are still delightful, but its background story and the feeling of lost potential tinge every chord with sadness.
Jimin - "Like Crazy"
BTS’s Jimin had long proved his prowess as a soloist (seen in "Lie," his 2016 solo released under the group), but it wasn’t until this year that he put forward a proper solo debut album. Out in March, Face presented Jimin at his truest: he co-wrote five out of six songs, and helped conceptualize the record and the music video for title track "Like Crazy."
Inspired by the 2011 movie of the same name, "Like Crazy" is a dark synth-pop journey through desperation. In the lyrics, Jimin tries to hold together whatever is left of a crumbling relationship. "I'd rather be / Lost in the lights, lost in the lights / I'm outta my mind / Can you help me numb the pain?" he pleads. Delivered with stirring mastery, the song resonated with audiences across the globe, leading Jimin to become the first South Korean to top Billboard’s Hot 100 chart.
Jisoo - "Flower"
After Jennie’s "Solo," Rosé’s R and Lisa’s Lalisa, BLACKPINK fans couldn’t be more eager for the quartet’s final member, Jisoo, to make her solo debut. Luckily, her single album Me came out in March, featuring lead single "Flower" and b-side "All Eyes on Me." At the time of release, Jisoo became the first K-pop female solo artist to become a million-seller, with Me exceeding 1.31 million pre-orders.
"Flower" is elegant and delicate, with pop synths that swirl around trap beats and lots of space. Traditional Korean music elements enhance its royal feel, while Jisoo’s husky vocals lament the loss of a relationship. Here, Jisoo proves her potential as a soloist, and opens the doors for BLACKPINK to begin a new era.
IVE - "I Am"
Another promising girl group to emerge in 2022, IVE are hitmakers with an empowering edge. From the meaning of their name ("I have") to their self-penned lyrics, the sextet aims to give the public as much confidence as they display on stage.
"I Am" spearheaded their first full album release in April, I’ve IVE, and quickly topped music charts in South Korea. With a disco flair reminiscent of ABBA, the single is a momentous celebration that reminds us to live life to the fullest. As they sing in the chorus: "That's my life, it’s a beautiful galaxy / Be a writer, the genre is fantasy / A big, big stage will open for me tomorrow / So that is who I am."
NCT DOJAEJUNG - "Perfume"
SM Entertainment’s decision to unite three of the smoothest vocalists under NCT into a subunit was one of 2023’s best decisions. Formed by Doyoung, Jaehyun and Jungwoo — or DOJAEJUNG — the trio released the unexpected but impeccable EP Perfume in April.
The eponymous title track encapsulates their vocal talents in a sultry R&B jam, overflowing with ‘90s nostalgia and heavenly harmonies. "I'll fill your day with heavenly scents / To remind you of my name at every step," they sing. Like the best perfumes, its notes spread and linger, creating a mesmerizing effect. Few songs flow so effortlessly.
Seventeen - "Super (손오공)"
Since their debut in 2015, one of K-pop’s most beloved acts, Seventeen, shows no signs of slowing down. The 13-member group continues to grow their fanbase and break records every year — 2023’s proof being their tenth EP released in April, FML. According to their agency, Pledis Entertainment, the EP sold 6.2 million copies — the highest sales ever in K-pop — and recently won Album of the Year at the 2023 MAMA Awards.
FML came with two lead singles, "F*ck My Life" and "Super," but it’s the latter’s grandiosity that stood out the most. Inspired by Sun Wukong, the mythological Monkey King of classic Chinese novel Journey to the West, the boisterous track blends Jersey club and bass drums into a larger-than-life celebration. "I love my team, I love my crew / We already made it this far," they sing, acknowledging what brought them to where they are.
Le Sserafim - "Unforgiven"
When the legendary Nile Rodgers chooses your song to be his first foray into K-pop, you must be doing something right. That is the case of Le Sserafim, the fearless girl group under Source Music (a sub-label of HYBE), and their May single "Unforgiven."
Off their debut studio album, also named Unforgiven, the track samples Ennio Morricone’s theme song from the 1966 film The Good, the Bad, and the Ugly, with Rodgers’ funky chords adding even more flair to a pop-country, hip-hop feast. "Never asked for forgiveness or anything / Gonna target taboos, watch me now," the quintet professes. Above all, "Unforgiven" is about freedom, and extends that concept to music creation as well.
aespa - "Spicy"
"Tell me what you see / When you look at me / ‘Cause I am a 10 out of 10, honestly," raps Giselle in the ultra-confident "Spicy." Off aespa’s third EP released in May, MY World, this gripping single provides the best of cheeky ‘90s pop mixed with rubbery synths and a revving pulse.
The SM Entertainment quartet gained attention upon their 2020 debut for incorporating avatars of themselves (æ-aespa) and an AI-inspired lore in their music. As their discography has grown, their concept and sound evolved to encompass new styles that reflect a bulletproof self-esteem. With "Spicy," aespa have proven to be more than just a hyper-tech fad, and entered main character territory.
(G)I-dle - "Queencard"
During a press conference for the release of their sixth EP in May, I Feel, the leader and producer of (G)I-dle, Soyeon, said that "the core message of 'Queencard' is that you can be a beautiful person if you adore yourself."
If you aren’t there yet, "Queencard" might just be the antidote. Here, (G)I-dle employ their megawatt charisma to deliver an irreverent, unabashedly pop track with hints of rock and roll. Part satire, part girl power anthem, "Queencard, I’m hot / My boob and booty is hot," is one of the most iconic lines of 2023, and if that doesn’t boost your self-esteem just a little, you might be taking yourself too seriously.
ATEEZ - "Bouncy (K-Hot Chilli Peppers)"
ATEEZ are one of the most commanding boy groups in K-pop. Since debuting in 2018, they captivate the stage: their facial expressions, knife-sharp choreographies, and hard-hitting sounds make it impossible to do otherwise.
Cut to 2023, when they made everyone "slow it down" and "make it bouncy," as goes the chorus of their June single "Bouncy (K-Hot Chilli Peppers)." Aside from the name reference, this has nothing to do with the Red Hot Chili Peppers — ATEEZ just wanted to show the world "A different kind of spicy, Cheongyang chili pepper vibe." It works. "Bouncy" is a tour de force in their discography, making a wild spectacle out of distorted, dystopian chaos.
NewJeans - "Super Shy"
2023’s definite hit of the summer came by the hands of NewJeans — the trailblazing girl group from HYBE’s sub-label ADOR. Their 2022 debut EP, New Jeans, took K-pop by storm, but this year proved they’re global stars to watch: the quintet was nominated Time's Next Generation Leaders, landed high fashion ambassadorships with brands like Gucci and YSL, performed at Lollapalooza in August, and released their sophomore EP in July, Get Up.
"Super Shy" is the album’s effervescent first single. "I'm super shy, super shy / But wait a minute while I / Make you mine, make you mine," they sing in flirtatious lilts, underpinned by UK garage and Jersey club beats. The result is a shot of pure pop serotonin.
NCT Dream - "ISTJ"
July’s "ISTJ" brings soaring harmonies and a propulsive melody to shape one of this year’s most enthusiastic hits. Off NCT Dream’s third studio album of the same name, it was inspired by the Myers-Briggs Type Indicator (MBTI) personality test, which is widely popular in South Korea. Individuals with the ISTJ personality type are said to be quiet and practical — nothing to do with the high-energy hip hop that NCT Dream portray in their song.
However, that’s because "ISTJ" is written from the point of view of their opposite type: ENFPs, who are usually the life of the party. Such a creative concept reinforces why NCT Dream keep on rising — from the teen sub-group made up of the youngest members from the collective NCT, they have now matured into charismatic leaders of their own.
AKMU - "Love Lee"
The first release in two years from sibling duo AKMU — formed by Lee Su-hyun and Lee Chan-hyuk — "Love Lee" is as lovely as it sounds. Out in August along b-side "Fry’s Dream," the track swept Korean charts since day one, and stayed atop the Circle Digital Chart (one of the biggest music charts in the country) for six non-consecutive weeks.
Initially unassuming, this jaunty ballad reveals its charms slowly, like honey dripping from a spoon. Su-hyun’s crystalline voice would be enough to steal the show, but here it is paired with sweet production quirks from Chan-hyuk, making the track a simple, yet memorable highlight of 2023.
RIIZE - "Get a Guitar"
For the past seven years, all male trainees under SM Entertainment eventually debuted in NCT — a larger group which holds several units like NCT 127 and NCT Dream. 2023 marked a change in that dynamic: in September, fresh-faced RIIZE launched their first single album, Get a Guitar.
The groovy title track is anchored by guitar plucks and retro synths, providing a feel-good introduction to their charms and a bright, light vibe to follow. Preceded by the wistful "Memories," Get a Guitar was a commercial success, receiving over 1 million pre-order sales — a new record for debut albums under SM. In 2024, these young men are sure to rise even higher, starting with an upcoming comeback on January 5.
Jung Kook - "Standing Next to You"
BTS’s youngest member Jung Kook took his time to officially launch a solo career. Since the band announced a break in group activities last year, he carefully directed his efforts to the Western market, releasing a series of collaborative singles like "Left and Right" with Charlie Puth, 2022 FIFA World Cup’s "Dreamers," "Seven" with rapper Latto and "3D" featuring Jack Harlow.
While all these songs are hits on their own, it turns out Jung Kook was saving the best for last. In November, he finally dropped his debut solo album, Golden, and title track "Standing Next to You." Inspired by the best of Michael Jackson, he moves through the song with conviction and poise, delivering a timeless hit for years to come.
