Woozi

Woozi (우지 | Lee Jihoon) is the production core of SEVENTEEN. Since the group's 2015 debut under Pledis Entertainment, he has shaped its musical identity with a level of authorship that very few idol-era stars can match at scale.

That role goes far beyond a token writing credit. Woozi has spent the last decade building SEVENTEEN's catalog from the inside, steering everything from the elasticity of early singles to the increasingly polished albums that turned the group into a stadium act. His KOMCA total sits in the hundreds, and his reputation inside K-pop is less about celebrity mystique than precision. He writes, arranges, records, revises, and keeps the machine moving.

His solo lane has sharpened that image rather than diluting it. The 2022 mixtape Ruby let him push harder into English-language pop-rock texture, while 2024 single What Kind of Future showed how emotionally direct his work can be. Even with military service beginning in September 2025, Woozi's place is already fixed. He is one of the defining idol-producers of his generation.

Fans Also Ask

Who is Woozi in SEVENTEEN?
Woozi, born Lee Jihoon on November 22, 1996, is the leader of SEVENTEEN's Vocal Team and the group's principal songwriter and producer. Since debuting with SEVENTEEN on May 26, 2015, he has become one of the clearest examples of an idol who genuinely builds a top-tier group's sound from inside the lineup.
How many songs has Woozi written?
Woozi holds songwriting and composition credits on hundreds of tracks through the Korea Music Copyright Association, covering most of SEVENTEEN's core discography plus outside work for other artists. The exact number keeps climbing, but his reputation is built on scale and consistency rather than a one-off hit or novelty credit.
Did Woozi release solo music?
Yes. Woozi released his first official solo project, the mixtape Ruby, on January 3, 2022. He followed it with the digital single What Kind of Future on January 26, 2024. Both releases matter because they show a more exposed version of his writing outside the group framework that usually defines his public image.
What instruments does Woozi play?
Woozi is known as a multi-instrumentalist with piano, guitar, clarinet, and drums in his working skill set. That training helps explain why his arrangements feel unusually complete for an idol-producer. He is not just sketching toplines. He understands how the underlying structure of a track needs to move.
Is Woozi in the military?
Yes. Pledis confirmed that Woozi began his mandatory military service on September 15, 2025. His enlistment arrived after a long run where he was central to SEVENTEEN's creative and commercial peak, so the current conversation around him is as much about legacy and continuity as it is about temporary absence.
