SM Entertainment founder Producer Lee Soo-man's (이수만) newly launched girl group, A2O LITE (에이투오 라이트), has made K-pop history! Their debut track, 'NEON,' released on October 13, 2026, soared to number one on Melon, Korea's largest music streaming platform, in just 29 hours. This unprecedented speed shatters the record for the fastest debut song by a rookie group to top the K-pop charts, garnering immense attention from both K-pop fandoms and the industry.
Producer Lee Soo-man's Return: The Dawn of A2O Entertainment
Producer Lee Soo-man made his grand return to the K-pop market through A2O Entertainment, a company he established in Singapore. This comeback follows the expiration of his three-year domestic music production ban in February 2026, which began after he sold his shares in SM Entertainment in 2023. In April 2026, he kicked off the 'A2O Zalpha Audition,' culminating in the debut show 'Welcome to Soulite From A2O SOUL A2O LITE' on October 12. There, he simultaneously unveiled a new vision with the 9-member multinational girl group A2O LITE and the 15-member boy group A2O SOUL (에이투오 소울).
A2O LITE comprises nine multinational members from Korea, Japan, the United States, China, and Thailand. At their debut, their average age was 14.9, and the group aims to embody the sensibilities of the 'Zalpha Generation' (a portmanteau of Gen Z and Alpha) through their 'Zalpha Pop' music. The group name A2O signifies 'Alpha to Omega,' symbolizing an endless creative process. Furthermore, Producer Lee Soo-man is incorporating innovation into their performance videos by utilizing '4DGS (4D Gaussian Splatting),' a new camera technology co-developed with Samsung Electronics.
Chart Domination! A2O LITE's Overwhelming Debut Performance
A2O LITE's debut song 'NEON' has swept both domestic and international charts. After hitting number one on Melon's 'TOP100' on October 14, it maintained its top position for 8 consecutive days, from October 15 to 22. The track also secured first place on the Circle Chart's 42nd-week Global K-POP Chart and Digital Chart, Spotify Korea Daily Chart, and Shazam Korea Chart.
Internationally, 'NEON' ranked 4th on Apple Music's 'Today's TOP 100: Global' and achieved number one across all three charts—New Songs, Trending Songs, and Music Video—on China's QQ Music. In Japan, it reached 2nd on Billboard JAPAN's 'Top User Generated Songs' and 5th on 'Hot Shot Songs.' It also made its first appearance on Oricon's Weekly Streaming Ranking and Weekly Digital Single Ranking (single track) on October 26, both at 48th place. The 'NEON' music video garnered approximately 3.7 million views on its first day of release.
A2O SOUL Enters Global Charts with Pre-Release Single
Meanwhile, A2O SOUL's pre-release single 'Superstar' music video surpassed 1 million YouTube views within a day of its release, climbing to 18th place on YouTube's Trending Music Chart. It also ranked 2nd on QQ Music's New Songs Chart (right behind A2O LITE's 'Neon'), 6th on the Trending Songs Chart, and 4th on the Global Music Video Chart. This impressive showing demonstrates the strength of A2O's groups, with both A2O LITE and A2O SOUL charting high simultaneously.
The Return of the 'SM Sound' and the Shadow of 'Age Controversy'
A2O LITE's rapid success is largely attributed to Producer Lee Soo-man's meticulous producing. On October 25, Girls' Generation's Sunny (써니) shared an Instagram post showing Producer Lee Soo-man personally demonstrating dance moves and providing detailed guidance to the members in the practice room. This revealed that his extensive K-pop production expertise is being directly passed down to the rookie group. Sunny congratulated A2O LITE on their music show win, expressing special affection for her juniors who received direct guidance from her 'uncle' (a respectful term for an older male mentor).
"I will pose questions to break free from K-pop mannerisms."

Fans are comparing A2O LITE's music to the 'SM sound,' reminiscent of SM stars like Girls' Generation, f(x), and BoA, and are reacting positively to their vocals, harmonies, and intricate choreography. According to an anonymous industry source, A2O LITE received over 50 advertising offers within just one day of their debut.
Average Age 15, K-Pop Idol 'Age Controversy' Reignited
However, a shadow of 'age controversy' looms over their success. A2O LITE members have an average age of 14.9, ranging from 13 to 17 years old. Notably, three members are 13 years old, leading to criticism among fans about whether idols at such a young age are truly prepared to endure rigorous training, demanding schedules, and public pressure. A2O LITE's youngest member, Aijing (아이칭), is 13 years and 5 months old. Furthermore, 13-year-old member Oa (오아) performing on stage in a short dress after debut also sparked controversy. While there is no legal minimum age for idol debut in Korea, this debate is expected to continue.
A2O SOUL, The 15-Member Boy Group's 'Superstar'
A2O SOUL (에이투오 소울), the 15-member boy group also produced by Lee Soo-man, is set to release their debut EP 'Superstar' on November 9. A2O SOUL consists of members from Korea, China, Japan, Thailand, and the United States. The Korean members are Moon (문), Seoha (서하), Hansung (한성), and See-one (씨원). Lucien (루시앙) holds both Korean and American nationality. Japanese members include Sora (소라), Gaku (가쿠), and Sono (소노). Teo (테오), Jun (준), Tai (타이), Zai (자이), Ayden (에이든), and Zet (젯) are from China, while Alure (알루어) is from Thailand.
Having already introduced themselves with a pre-release single of the same name, A2O SOUL plans to officially kick off their activities by releasing a total of five tracks, including 'Superstar' and their second title track 'Dancing in the Dark,' across major streaming platforms. A2O Entertainment stated, "Producer Lee Soo-man personally guided the album's musical direction and hand-picked world-renowned composers he had not worked with before, creating fresh musical synergy to enhance the overall completeness of the album." 'Superstar' is a 'New Synthwave' genre track characterized by delicate melodies and synthesizer sounds. The physical album will be released in three versions: 'SOUL,' 'CONSTELLATION,' and 'CARABINER.' Each version includes a photobook, paper mobile, lyric sheet, CD, and photocard, increasing their collectible value for fans.
