After Billboard named “Blue Valentine” the No. 1 K-pop song of 2025 — and its parent album the year’s second-best — the NMIXX group chat lit up.
“We were like, ‘Oh my God, this is crazy,’ ” recalls Australia-raised Lily. “We were all so happy.” But the critical adoration, Lily is careful to add, comes second to what their fans — known as NSWERs — think. “We did work hard to get to this place where Blue Valentine could be recognized like that, so it does really feel validating,” the vocalist shares. “But obviously, the most important thing to NMIXX always will be our NSWERs’ reactions and thoughts on our album.”

In 2026 alone, NMIXX has collaborated with Brazil’s drag icon Pabllo Vittar on “TIC TIC” and contributed a single for Anderson .Paak’s forthcoming K-Pops! film soundtrack — two partnerships that reflect the group’s growing stature in the music industry at large and the range of genres they want to tackle. NMIXX leader Haewon has even been studying Spanish with a purpose that speaks to the group’s aim to reach as many listeners as possible.
“We’re trying to cater to a really diverse audience,” she says. “Our songs do that, so I wanted to learn a global language [like Spanish] to help connect with more fans across the world.” The recognition Haewon received after speaking to the crowd in Spanish at Chile’s Viña del Mar International Song Festival — a stage known for an unforgiving audience — was, Haewon says, proof the effort was worth it. And she’s already looking further ahead: “If we have the chance, we really, really would like to release more music in Spanish” as a follow-up to 2023’s “Soñar” plus their Pabllo Vittar collabs.
For NMIXX, validation has been a long time coming for a group that, since its 2022 debut, has operated by sticking valiantly committed to pushing the K-pop scene into new global markets and experimental sounds. Their current world tour is called Episode 1: Zero Frontier, a title that functions as both a statement of arrival and promise of more to come. With a new EP, Heavy Serenade, out next month, NMIXX appear just as curious to see where and what areas they can potentially conquer next.
“It’s going to be great,” Lily says of the release. “ We’re definitely not going to go away anytime soon.”

Foundation
Announced seven months prior to the act’s debut in February 2022, JYP Entertainment built buzz for NMIXX before it joined the label’s historic roster of girl groups that also includes Wonder Girls (the first K-pop act to enter the Billboard Hot 100) and TWICE (which has seven top 10s on the Billboard 200). The group’s name is partly inspired by its self-coined “mixx pop” genre, mashing unexpected sounds and styles like hopping between baile funk and anthemic rock on debut single “O.O” or utilizing boom-bap and tempo changes for the emotionally charged “Blue Valentine.” The latter earned the act its first entry on the Mainstream Top 40 chart in January, spending seven weeks on the list. “NMIXX’s whole message is about the importance of diversity and how, especially in music, everyone deserves a spot at the table,” Lily says. “The beauty of music allows people from all over the world and all different types of people to come together for this one beautiful thing. I hope that it’s helped a lot of our NSWERs who feel left out to feel included with our music.”
Discovery
After a 2023 showcase for fans in cities including New York, Los Angeles and Houston — plus appearances at iHeartRadio’s Wango Tango, KCON and on a panel at Billboard’s 2024 Latin Music Week, where the group sang in Spanish — NMIXX is making ample time for the West in 2026. The sextet performed its new Pabllo Vittar collaboration, “TIC TIC,” at São Paulo’s Carnival (“It was the most amazing energy I’ve ever received onstage,” Kyujin recalls) before Chile’s Viña del Mar International Song Festival welcomed the act as its first Korean performer (“We were worried because we heard the audience reacts very honestly and won’t hide it if they want us to wrap it up, but the response was amazing,” Sullyoon says). The group’s performances previewed five U.S. dates on NMIXX’s Episode 1: Zero Frontier World Tour, beginning with a sold-out show at the Brooklyn Paramount on March 31. “Last time was a showcase, so I feel like it was a taste of NMIXX,” Lily says. “This time is the whole meal.”
Kyujin adds, “The theme of this tour is the first journey that we’re taking with fans — and we are planning to have many, many more. So, we hope you can stay together with us through all of that.”
Future
The tour is scheduled through August, but future plans are already in motion. “We’re traveling the whole world and encountering music from all different countries, so I think we’re going to continue to be inspired by different types of artists and genres,” Lily says, adding that she and Bae cherished the Bad Bunny show they saw in Brazil. “This is our first full concert tour, so that’s why it’s ‘Episode 1’ — it implies that there might be more.” More immediately, NMIXX has a spring single dropping for the soundtrack to Anderson .Paak’s 2026 K-Pops! film, plus a forthcoming EP, titled Heavy Serenade, out on May 11. ”It’s even more diverse,” Haewon teases. “We’re always experimenting and trying out new, different types of music.”
While Blue Valentine marked the first time the NMIXX members scored songwriting credits on a project, Heavy Serenade features Lily co-writing intro song “Crescendo” and is the sole songwriter of another new track, “LOUD,” while Bae co-wrote “Different Girl.” Lily predicts that the six will continue to collect creative credits as they move forward in their careers. “A lot of our members are really interested in songwriting,” she says. “Hopefully, a few of us can keep writing music for NMIXX for the next one.”
