Development
Kep1er was formed in 2021 as a temporary multinational girl group through Mnet's survival competition program Girls Planet 999, which selected nine members from applicants across South Korea, Japan, and China: Choi Yujin, Sakamoto Mashiro, Shen Xiaoting, Kim Chaehyun, Kim Dayeon, Ezaki Hikaru, Huening Bahiyyih, Kim Youngeun, and Kang Yeseo. Originally consisting of nine members, the group continued as seven following the departure of Sakamoto Mashiro and Kang Yeseo in July 2024.[11][12] The group's name, stylized as "Kep1er," draws from astronomer Johannes Kepler to represent the members uniting as one ("1") to catch and pursue dreams, reflecting their aspirational concept.[13] The group's debut was originally planned for December 14, 2021, with the release of their first mini album First Impact, but it was delayed to January 3, 2022, after a staff member tested positive for COVID-19 on December 4, 2021, prompting quarantine measures.[14] On December 14, 2021—the initial debut date—members Mashiro and Xiaoting were confirmed to have asymptomatic COVID-19 cases, with the remaining members and staff testing negative; this further necessitated the postponement to ensure safety.[15] Both affected members fully recovered by December 26, 2021, allowing promotional activities to resume ahead of the revised debut.[16] "Wa Da Da" was chosen as the title track for First Impact to encapsulate Kep1er's vibrant, youthful energy and theme of chasing dreams, aligning with the group's unified identity and multinational appeal.[5][17] The track was produced under the supervision of WakeOne and Swing Entertainment, the agencies managing the group, with credits to producers including Shannon Bae and Odal Park, emphasizing a big room house sound to highlight the members' dynamic charm and broaden international accessibility.[18][19][20]Release history
"Wa Da Da" was released digitally on January 3, 2022, as the title track of Kep1er's debut extended play (EP) First Impact, through WakeOne Entertainment.[21] The EP became available on major streaming platforms including Spotify, Apple Music, and Melon, marking the group's official debut following their formation on the survival show Girls Planet 999.[22] Physical editions of First Impact were also released on the same date in three versions—Connect, Connect O, and Connect 1—each containing a CD along with a photobook, digipack, two random photocards, a random postcard, and a sticker.[23] Distributed by Genie Music and Stone Music Entertainment in South Korea, the physical mini-album carries the catalog number CMAC11699.[24] No vinyl editions were produced for the initial release.[23] A Japanese version of "Wa Da Da" was released on September 7, 2022, as the fourth track (b-side) on Kep1er's debut Japanese single Fly-Up (Special Edition), under WakeOne.[25] This adaptation features lyrics translated into Japanese while retaining the original dance-pop structure, and it was made available digitally and in physical CD formats as part of the single's multiple editions.[26]Composition and lyrics
Musical composition
"Wa Da Da" is a dance song in the big room house genre, incorporating electronic dance music influences characterized by heavy percussion, swerving synths, and a stomping beat. The track is composed in the key of B-flat major, runs at a tempo of 126 beats per minute, and has a duration of 3:04.[27] The song employs a verse-chorus structure, beginning with crunchy rap verses that establish a bold tone, followed by a pre-chorus build-up featuring strong, soaring vocals.[28][29] The chorus centers on a hooked refrain of "Wa Da Da Da," divided into two parts: an initial sassy segment that aligns with the track's energetic vibe, transitioning into a second half with high-pitched elements and a gritty, distorted drop highlighted by rich bass.[28][30] Instrumentation prominently features bass drops and electronic synths that drive the high-energy atmosphere, complemented by vocal chops integrated to amplify the overall dynamism.[30][29] This combination creates an unapologetically vibrant banger reminiscent of high-energy dance tracks by groups like IZ*ONE, yet distinguished by a broader global EDM edge.[29]Lyrics and theme
The lyrics of "WA DA DA" center on themes of aspiration and unity, portraying a collective journey toward dreams with unyielding determination and encouragement for listeners to join in.[5] Drawing from the group's name—where "kep" signifies capturing a dream and "1" represents being the best—the song invites fans to "take off" together, emphasizing shared ambition and resilience in the face of challenges.[17] The repetitive chorus hook, Wa-da-da-da, running vroom-vroom-vroom like a supersonic, evokes high-energy momentum, mimicking the thrill of rapid pursuit and serving as a chant-like symbol of enthusiasm and hurried excitement.[31] Key verses blend English and Korean for global accessibility, with lines like the opening Hey! It's you, and I, let's start calling for partnership, and Korean phrases such as 어딨니? 나 보이니? 자, 시그널을 보낼게 catch it (Where are you? Do you see me? Here, I'll send a signal, catch it) fostering a sense of connection and visibility in the adventure.[5] The bridge reinforces perseverance with Even when I'm out of breath, I won't give up, run, run, run, highlighting endurance.[31] A notable wordplay in the post-chorus, Kep 1 going WA DA DA DA, directly nods to Kep1er's identity while amplifying the song's motivational drive, blending linguistic elements to reflect their multicultural formation.[17] Written by a team including BuildingOwner, Elum, and Hwang Yu-bin, the lyrics capture the youthful charm and post-debut determination of the nine members, who emerged from the survival program Girls Planet 999, channeling their competitive spirit into an uplifting narrative of collective success.[5][17]Promotion

Reception and legacy
Critical reception
Critics praised "WA DA DA" for its energetic vibe and vibrant production, with NME describing it as an "unapologetically vibrant banger" that evokes the high-energy style of the disbanded group IZ*ONE.[29] The track's crackling energy and exciting beat drop were highlighted as strong elements, contributing to its appeal as a dynamic debut.[50] Mixed reviews noted the song's catchy yet underdeveloped chorus, with The Bias List rating it 7.75/10 and calling it "serviceable fun" bolstered by swerving synths but undermined by a lackluster, gibberish-filled hook that lacks melodic depth.[50] Similarly, Kpop Reviewed awarded an overall 6.9/10, acknowledging its potential as a promising debut but critiquing flaws like inconsistent energy and a childish title hook that creates holes in its solidity.[28] The overall consensus positioned "WA DA DA" as a solid debut with global potential, averaging around 7/10 across major reviews, appreciated for its choreography and the group's charming synergy but viewed as safe and trend-following rather than innovative.[50][28][51] Media outlets like KBopped emphasized its percussive appeal and forceful deep house influences, rating it 7.25/10 for the strong verse-group synergy despite a chaotic chorus.[51]Accolades

Cultural impact
"Wa Da Da" solidified Kep1er's identity as a dynamic, high-energy girl group from their debut in January 2022, with its upbeat big room house sound and vibrant choreography capturing the essence of youthful ambition and unity. The song's repetitive "Wa Da Da" hook quickly evolved into a signature fan chant and motivational slogan within the Kep1ian community, often chanted during concerts and online rallies to energize supporters.[60] The track's longevity is evident in its continued inclusion in Kep1er's setlists through 2024 and 2025, even following the group's contract extension as a seven-member unit after Mashiro and Yeseo departed in July 2024 due to agency disputes. Performances at events like KCON LA in July 2024 and August 2025, where they delivered the song, and special stages at The Fact Music Awards in September 2024 highlighted the song's enduring appeal, adapting to the group's evolving lineup while maintaining its core energy. By November 2025, the official music video had amassed 184 million views on YouTube, a milestone first reached in April 2022.[61][62][63][10][64] In fan culture, "Wa Da Da" sparked widespread engagement, including covers and TikTok dance challenges that replicated its infectious choreography. Detailed fan analyses of line distribution further amplified member spotlights, with leader Yujin receiving the highest share of vocals at approximately 18.5% of the song's lines, fueling discussions on vocal equity in large ensembles. These elements fostered a dedicated online fandom, blending creativity with analytical discourse.[65] On a broader scale, the song's success bolstered the project group model in K-pop, proving its potential for long-term viability as Kep1er became the first survival program-formed act to secure a contract extension without disbanding in 2024. Debuting amid the post-pandemic recovery, "Wa Da Da" symbolized resilience in the industry, embodying themes of relentless pursuit from the Girls Planet 999 survival show through lyrics urging listeners to "run around and round, don't stop" in dream-chasing adventures.
