In a historic moment for SEVENTEEN and its diversifying sub-units, Billboard officially announced on January 27, 2026, that the group’s newest powerhouse duo, DxS, has made their grand debut on the Billboard 200.
Comprised of vocal powerhouses DK and Seungkwan, the unit has successfully translated their immense domestic popularity into significant chart success in the United States.
Their debut mini-album, “Serenade,” has proven to be a global favorite, marking a new chapter for the duo as they establish a distinct musical identity separate from the full group’s activities.
Chart Performance and “Serenade’s” Success
According to Billboard’s rankings for the week ending January 31, 2026, “Serenade” entered the Billboard 200 at No. 195.
While the Billboard 200 tracks overall popularity across streaming and sales, the album’s performance in pure sales was even more impressive. “Serenade” debuted at No. 6 on both the Top Album Sales chart and the Top Current Album Sales chart.
This means that, for the week of its tracking period, DK and Seungkwan’s unit debut was the sixth best-selling album in the United States, outperforming many mainstream domestic releases.

Furthermore, the mini-album dominated the genre-specific charts, claiming the No. 3 spot on the World Albums chart.
This multi-chart presence underscores the strength of the SEVENTEEN brand in North America and the specific appeal of the DK-Seungkwan vocal combination.
Individual Recognition on the Emerging Artists Chart
The success of “Serenade” also translated into individual accolades for the two members. On Billboard’s Emerging Artists chart, which tracks the rise of developing talent in the U.S. market, both idols made significant entries.
DK debuted at No. 7, while Seungkwan followed closely behind at No. 8. This individual recognition is a testament to their star power and the high level of interest in their artistic growth beyond the collective identity of SEVENTEEN.
The Musical Identity of DxS
The unit name “DxS” is a straightforward representation of the two vocalists, but their music offers a deep, emotive experience.
“Serenade” focuses on showcasing the incredible vocal range and harmonic synergy that DK and Seungkwan have honed over a decade of performing together.
Known as the main vocalists of SEVENTEEN, the duo utilized this project to explore genres that highlight their storytelling capabilities and emotional delivery, moving away from high-energy dance tracks to more melodic and vocal-centric compositions.

Future Outlook and Global Impact
The Billboard debut of DxS is a clear indicator that SEVENTEEN’s strategy of promoting specialized units—such as BSS (BooSeokSoon) and now DxS—is highly effective in maintaining global momentum.
As the members continue to balance group activities with unique unit projects, they are reaching different segments of the music-listening public.
Fans, known as CARATs, have celebrated this achievement across social media, noting that the duo’s success on the U.S. charts is well-deserved after years of consistent hard work.
With “Serenade” continuing to perform well on various global charts and the duo participating in major domestic music shows like “M Countdown,” the future for DxS looks exceptionally bright.
This Billboard debut not only solidifies their personal legacies but also reinforces SEVENTEEN’s position as one of the most versatile and commercially successful acts in the modern music era.
