Korean songs you often hear on TikTok. Trending K-pop (21–30)
SPAGHETTI (feat. j-hope of BTS)LE SSERAFIM
A track featuring BTS’s j-hope was released in October 2025.
Issued as the title track of the group’s first single album, “Spaghetti,” it blends alternative pop and funk, weaving bouncing bass with tight, hard-edged drums.
Packed into a runtime of just over two minutes, the song is engineered for high addictiveness, delivering hook after hook.
Like spaghetti intertwining, the lyrics unfold self-referential metaphors—“it won’t leave your head,” “it’s addictive”—positioning LE SSERAFIM themselves as an irresistible presence.
The concept is intriguing, and international reception has been strong, including their first-ever top-50 entry on the UK charts.
It’s a track that showcases a fresh charm—pop-savvy with a vibrant street feel.
Eve, Psyche & The Bluebeard’s wifeLE SSERAFIM
If you’re looking for that song you keep hearing where the same word gets repeated, you might be thinking of “Eve, Psyche & The Bluebeard’s wife.” It’s a hip-hop track by the girl group LE SSERAFIM.
The powerful chorus makes a big impact, and the cool, easy-to-copy choreography is another reason it went viral.
It’s fun to watch and listen to, and it’s also perfect if you want to try filming a dance video yourself.
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.
FEARLESSLE SSERAFIM
The girl group LE SSERAFIM, whose debut made big headlines in Japan, is creating a buzz on TikTok with collaboration videos with the boy group SEVENTEEN.
In the clips, members of both groups dance to LE SSERAFIM’s debut single “FEARLESS.” The performances are genuinely captivating, so even if you’re not a fan of either group, I recommend checking them out.
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.
