STAYC's 'S' Album: The Hidden Story Behind Their Bold New Sound

STAYC, the K-pop group known for their bright bubblegum pop hits like "ASAP" and "Teddy Bear," has undergone a striking transformation with their fifth single album "S" released on March 18, 2025.

Since their debut under High Up Entertainment in November 2020, the group's musical journey has evolved significantly. Their latest comeback marks a bold departure from their previous sound, featuring three tracks that blend funky house and R&B elements. The title track "Bebe" showcases this new direction, delivering a powerful message about defying stereotypes while incorporating fresh musical elements that signal a more mature artistic vision.

STAYC’s journey from debut to now

In November 2020, a new girl group emerged in the K-pop landscape when STAYC made their highly anticipated debut under High Up Entertainment. The six-member group, consisting of Sumin, Sieun, Isa, Seeun, Yoon, and J, introduced themselves with their first single "So Bad" from their debut EP aptly titled "Star To A Young Culture."

How STAYC debuted with 'Star to a Young Culture'

The group's name itself carries significance—an acronym for "Star To A Young Culture"—reflecting their mission to become role models for the younger generation. Their debut showcased the production talents of Black Eyed Pilseung, the hitmaking duo behind the company. Initially, STAYC established themselves with a distinct "teen fresh" concept, blending youthful energy with polished performance skills. Their debut track "So Bad" introduced audiences to their signature sound characterized by catchy melodies and colorful visuals.

Key milestones in their discography

Following their debut, STAYC quickly built momentum with a series of successful releases. Their breakthrough came with "ASAP" from their second single album "STAYDOM" in April 2021, which propelled them into mainstream recognition. Subsequently, they released "Stereotype" as their first mini-album title track in September 2021, further cementing their position in the industry.

Throughout 2022 and 2023, STAYC continued to expand their musical portfolio with releases like "RUN2U," "BEAUTIFUL MONSTER," and the particularly successful "Teddy Bear," which showcased their versatility while maintaining their distinctive sound. Notably, each comeback demonstrated growing confidence and artistic maturity, gradually building toward their current identity.

Shifts in concept and sound over the years

STAYC's musical evolution can be traced through their changing concepts and sound. Initially focused on bright, teen-fresh concepts with bubblegum pop elements, the group has gradually incorporated more mature themes and diverse musical influences. Their early work featured straightforward pop production, whereas later releases began experimenting with different genres and more complex arrangements.

Before the release of "S," STAYC had established a recognizable sonic identity rooted in upbeat pop melodies with catchy hooks. However, each release subtly pushed boundaries, preparing both the members and their fans for the more dramatic shift that would come with their fifth single album. This gradual evolution makes their current R&B and house-influenced direction feel like a natural progression rather than an abrupt change.

What makes the 'S' album different

STAYC's fifth single album 'S' represents a dramatic pivot in the group's musical identity, marking their boldest sonic and visual reinvention since debut. Released after a five-month hiatus, this album showcases the six-member group embracing a completely new direction.

A new sound: from bubblegum pop to R&B and house

The album pulses with intense, fast-paced bass and house beats, a complete departure from their previous bubblegum pop sound. Their title track "BEBE" features funky house rhythms with bold bass lines and energetic beats, creating a dance floor-ready experience that bears little resemblance to earlier hits like "ASAP" and "Teddy Bear".

Beyond the title track, "DIAMOND" introduces contemporary R&B infused with Afro rhythms, while "PIPE DOWN" showcases a pop-R&B sound characterized by catchy brass instruments. This musical evolution also includes experimentation with ballroom and voguing influences, adding sophisticated layers to their previously straightforward pop approach.

Visual transformation and concept change

Visually, STAYC has traded their bright, youthful aesthetic for a high-fashion, editorial-inspired look. The "BEBE" music video features avant-garde styling with bold typography reminiscent of luxury fashion spreads. This transformation aligns with the album's overarching theme of "Sensual, Sophisticated, Self-esteem", signaling their maturation as artists.

Sieun explained the evolution: "It was the label and producer who first proposed the idea of trying a bold concept. But once we heard the track, we knew we could do this".

Why this shift matters in their career

This transformation arrives at a crucial moment for STAYC, establishing them as versatile artists capable of transcending K-pop archetypes. The members themselves recognize this significance, with Sumin noting: "With this album, I think we can really establish that we're not just a cute and refreshing group but also a group that's more daring than people thought".

Additionally, this shift challenges traditional representations of female K-pop groups, moving beyond the innocent/sexualized binary often imposed on them. Instead, STAYC presents a more complex identity celebrating strength, vulnerability, and self-assuredness.

Breaking down the tracks on 'S'

The three tracks on STAYC's 'S' album showcase the group's impressive musical range and artistic growth, with each song revealing a different dimension of their new sound.

Bebe: A bold title track with a message

"BEBE" stands out as STAYC's most confident title track to date, built on an infectious funky house rhythm designed to make listeners move. The track features bold bass lines and energetic beats, creating an engaging dance floor experience that's both fresh and memorable. At its core, the standout hook "Don't wanna be a bebe" serves as more than just a catchy phrase—it's a declaration of authenticity and self-assurance.

The song balances poppy elements with a distinct disco/house vibe, exploring the exciting feelings that come with a crush. The members' vocal performances shine throughout, with Sieun's stylistically "lazy" delivery in the chorus adding a unique flair that enhances the track's distinctive character.

Diamond: Letting go of fear through rhythm

"DIAMOND," the album's second track, presents a contemporary R&B sound infused with captivating Afro rhythms that highlight STAYC's vocal versatility. At just 2 minutes and 22 seconds, this compact song makes a powerful impact through its message of self-confidence.

The lyrics encourage listeners to release their fears and embrace a bright future, using the diamond—a symbol of strength and resilience—as a metaphor for personal growth. Lines like "Make you see that, that I'm strong enough" and "Nobody can hurt you, you're so beautiful" reinforce the empowering theme that runs throughout the album.

Pipe Down: A confident, brass-heavy closer

The final track, "PIPE DOWN," delivers a pop-R&B sound characterized by distinctive brass instruments that add a new dimension to STAYC's musical repertoire. This assertive song creatively plays with the concept of a "mute button," symbolizing the group's bold stance toward expressing their opinions and defying expectations.

Clocking in at just under two and a half minutes, "PIPE DOWN" maintains the album's concise yet impactful approach. The track encourages listeners to stand up for themselves and ignore those who try to bring them down, completing the album's narrative arc with a message of empowerment. The hip-hop influenced choreography features exaggerated "swag" movements that complement the song's confident energy.

Fan and industry response to the comeback

The reception to STAYC's musical evolution with the 'S' album has generated ripples throughout the K-pop community, reflecting both excitement and adjustment as fans and critics digest their bold new direction.

How fans reacted to the new sound

Fan response to STAYC's dramatic shift has been notably diverse. Many longtime SWITH (STAYC's fanbase) expressed immediate enthusiasm, with some calling "BEBE" "the best K-pop release of the year so far". Indeed, the track quickly became an earworm for many, despite its departure from the group's established sound. Nevertheless, others found themselves struggling to connect with the new direction, particularly those who had grown attached to the bubblegum pop style of previous hits. This division reflects the inherent challenge of artistic evolution—balancing innovation with established identity.

Music show wins and chart performance

STAYC has continued their impressive record of music show success with "BEBE," adding to their collection of 21 music show wins accumulated throughout their career. Prior to this comeback, the group had secured multiple wins for previous releases including 5 wins for "Teddy Bear" and 7 wins for "RUN2U". Beyond music shows, their chart performance demonstrates sustained popularity across platforms.

Music critics have generally praised STAYC's evolution, with publications highlighting the group's willingness to push beyond comfortable territory. NME specifically commended 'S' for showcasing "the girl group's impressive range" and proving "STAYC's timeless charm and staying power". Furthermore, critics noted how this comeback represents a "return to the energy that first caught them attention, but now with a renewed sense of identity". Even mixed reviews acknowledge the group's ambition, recognizing their exploration of "new soundscapes and subject matter" as a sign of artistic maturity.
