Widely known as the "Queen of K-pop," BoA's music and the influence has transcended generations and cultural barriers. Her presence marks a clear before and after in the K-pop industry.
Throughout her 25-year career — a milestone she will be commemorating on Aug. 25 — BoA has been recognized for her ability to reinvent herself. On acclaimed albums like Hurricane Venus and fierce tracks like "Girls On Top," she has navigated a broad range of genres with a specific star quality.

In the early days of Korean pop, teenage BoA caught the eye of scouts at SM Entertainment, who signed her immediately. She then spent two years honing her skills before debuting with her first studio album, ID; Peace B, in August 2000. While the album received a measured reception, BoA's professional path soon took a turn to focus on Japan — a strategic, albeit difficult, move that defied expectations by entering a market long considered off-limits due to historical tensions between the two countries.
BoA won over Japanese audiences with her mesmerizing voice and dancing ability. Her first Japanese album, 2002's Listen to My Heart — which produced emblematic songs such as "Amazing Kiss" and "Every Heart," the ending theme for the anime "InuYasha" — signaled a promising future. Eventually, BoA became the first South Korean artist to dominate Japan's most important charts and sell millions of records in the country.
In addition to straddling the worlds of Japan and Korea, BoA is notable for her ability to inhabit a spectrum of musical personas with ease. Her repertoire is a journey in itself: from ballads like "Meri Kuri," Japan's quintessential Christmas anthem, to dance-pop bursts that ignite the spirit, such as "Double," and anthems of empowerment and self-assurance, like "Woman."
As her career progressed, BoA gradually assumed full creative control, ultimately shaping the artistic vision that would define her future projects. (For instance, her 2015 album Kiss My Lips was the first to be entirely structured by her.) Notably, she was one of the first Korean pop artists to make a foray into the U.S. market and even starred in the Hollywood dance film Make Your Move.

Today, BoA is recognized as a legend and a trailblazer among both male and female idols. She continues to exert a major influence on K-pop, particularly through her work as a mentor. She now steers NCT WISH in her role as producer.
With a catalog spanning countless albums, singles, and collaborations, capturing it all here would be impossible. These five songs, however, offer a window into the artistry of one of K-pop’s most influential figures as she celebrates 25 years since her debut with the release of her newest album, Crazier, out on Aug. 4.
"No.1" (No.1, 2002)
Among all the works in BoA's extensive catalog, "No.1" will forever be immortalized as one of K-pop's greatest, with the artist herself even describing it as "a song that gifted me the most meaningful and happiest moment of my career so far."
BoA was just 15 when she released this title track from her second Korean, and it rapidly received widespread acclaim. Following its Korean premiere by a few months, the Japanese version, "Kiseki / No. 1," replicated its levels of success.
The formula was succinct yet impactful: a pop song in its purest form. However, its melodic strand flows in both hope and nostalgia, telling the story of a girl whose heart longs for a love she once had, claiming — in the unforgettably catchy chorus — that "you're still my number one." And while the energy channels all the yearning and bravado that an adolescent BoA could muster, her vocals have long been splendid.
The "Queen of K-pop" continues to perform this track, which is a cornerstone of her legacy.
"Valenti" (Valenti, 2002)
If songs like "Amazing Kiss" and "Listen To My Heart" were BoA's opening statement in the Japanese music industry, "Valenti" confirmed her star power.
A fateful love courses through beats of dance-pop and Latin rhythms, all driven by BoA's crescendoing voice. From the very first listen, the song is irresistible as a siren's call, and complemented with the music video, it's BoA's dance prowess that seals the deal. She made it clear she had arrived to stay and reign.
With "Valenti," which eventually had versions in Korean and English, BoA achieved her first top three single on the Oricon charts and made her inaugural appearance at the 2002 Kōhaku Uta Gassen, Japan's most prestigious year-end music program. When the album later arrived in early 2003, it sold over 1.2 million copies, becoming the best-selling Japanese record of her career.
"Only One" (Only One, 2012)
Only One is BoA's seventh Korean album and is widely considered to be an artistic rebirth, drenched in wisdom that only time and experience can bring.
Only One claims special significance in BoA's trajectory for several reasons. Among those, the album's title track was the first song BoA fully composed and wrote herself. Rather than yielding to the hip-hop beats that were prominent during that era, BoA crafted a warm R&B ballad ornamented with sweet-and-sour guitar strings and piano chords that spur the most heartfelt sentiments to bloom.
Her voice, more stunning than ever, lifts the listener to an emotional height. Throughout, she ad-libs about the pain of a breakup, later offering solace as we come to accept that it’s time to let go.
BoA didn't hold back in the choreography, which was created by Emmy-winning duo Nappytabs. The routine showcased why BoA is truly stellar, harmonizing power with elegance in every move. Furthermore, the pinnacle of the choreography included a now-iconic duet that she still continues to perform with some of the most skilled K-pop idol dancers across generations.
"Better" (Better, 2020)
With nothing to prove and everything to celebrate, BoA's 20th anniversary arrived as an opportunity to reflect on her journey with pride while still inspiring with the same passion that defined her debut.
"Better," the eponymous single from her tenth Korean full-length album, was a creative homecoming of sorts, reuniting BoA with the genius of Yoo Young-jin, former star producer and songwriter at SM Entertainment. The duo revived the early-2000s’ sensual melodies, which swell in pulse until reaching an interlude where BoA flaunts her unmistakable vocal control. Then, the conclusion is exceptional, as she throws herself into the performance without restraint.
The song is already categorized as a K-pop classic, having resonated with longtime fans while also introducing BoA's magic to a new generation of listeners.
"What She Wants"(Crazier, 2025)
Crazier, BoA's newest album, spans genres and continues to showcase the versatility BoA has displayed throughout the years. B-side "What She Wants" is worthy of single status and enthralls from the opening seconds, riding the tempo of BoA's riveting tone.
The production is pristine, with a deep bassline that runs steadily before pausing for a respite in the pre-chorus, then picking up again with playful nostalgia. In the middle of the journey, the arrangement thickens with additional layers, and the track unfolds like a rollercoaster: it gradually climbs through the bridge before plunging into the exhilaration of the outro's freefall.
