Korean songs you often hear on TikTok. Trending K-pop (21–30)
Blue ValentineNMIXX
The title track from NMIXX, the girl group under JYP Entertainment, off their first full-length album “Blue Valentine,” released in October 2025.
Embodying the album’s key theme of the paradox of love, the song paints the pain that comes precisely from loving deeply in shades of “blue.” Opening with melancholic synths, it blends boom‑bap rhythms with pop‑rock‑leaning guitar riffs—an elevated take on NMIXX’s signature “MIXXPOP.” From mid-October, it took first place consecutively on five major Korean music programs and made its presence felt on charts at home and abroad.
A track that stirs listeners’ emotions with a driving sound imbued with poignant sorrow.
LOVE DIVEive
The song that’s gone viral on TikTok for its cute choreography using a thumbs-up gesture is LOVE DIVE.
If you’re a TikTok user, you’ve probably seen that dance at least once.
The track is performed by the girl group IVE.
Although it has an upbeat, fun vibe, the lyrics actually depict the pain of unrequited love.
By the way, IVE calls their fans DIVE.
In other words, the title carries a double meaning.
ELEVENive
IVE’s spectacular debut track, which won 13 crowns on music shows and surpassed 100 million streams in Korea.
It blends an oriental vibe reminiscent of BLACKPINK with the glamorous presence of members like former IZ*ONE’s Yujin and Wonyoung in exquisite harmony.
This captivating number shines with the sparkle of first love.
Its distinctive pre-chorus and chorus parts leave a strong impression, sparking a trend of dance cover videos.
It enjoys high popularity among K-pop fans, especially junior high and high school girls.
MANSAESEVENTEEN
SEVENTEEN, whose recent dome tour in Japan is still fresh in our memories, have a track I highly recommend for enjoying the vocal skills of all 13 members: “MANSAE.” You’ve probably seen this song a lot in TikTok dance videos.
In particular, videos that recreate the chorus—featuring the memorable side steps—have gone viral.
The choreography is relatively easy to imitate, so give it a try.
There are also videos that break down the moves, so it might be helpful to use those as references.
OMGNewJeans
“OMG,” a dance video set to a chill beat that’s been trending on TikTok, was released in 2023 by NewJeans, a girl group that has won numerous music awards in Korea.
The soft, airy synth tones gently resonate, matching lyrics that portray a heart growing fuller after meeting a loved one.
Their sweet, glossy choral work lets you feel the rising emotion in their vocals.
Paired with their cute bunny-costume choreography, it’s a track that lays down an R&B-style groove.
AttentionNewJeans
The song that’s been making waves not only across Asia but also in the United States is “Attention.” It’s the debut single from NewJeans, a girl group that debuted in 2022.
The group drew buzz because details about them were kept under wraps until their debut.
Another reason it garnered attention is that, unusually for an idol group’s debut single, it has an R&B vibe.
Among music fans, many also praise its excellent key changes.
Be sure to listen with that point in mind.
CASE 143Stray Kids
Have you checked out Stray Kids’ “CASE 143”? It’s a striking track where the A and B sections are stylish, and then the chorus shifts key and drops into a low, ominous vibe.
This structure is said to reflect how “love” is portrayed as a case, expressing the instability it causes in the heart.
By the way, the “143” in the title is a code that means “I love you.” Keeping that in mind will help you enjoy the world of the song even more.
