Choi Yeonjun, a member of the K-pop group Tomorrow X Together, has expanded his solo career through a debut EP and a global sports anthem.

These milestones signal a strategic transition for the artist as he establishes an individual identity outside his group activities. By blending solo music chart success with high-profile international collaborations, Yeonjun is positioning himself as a versatile global performer.

Yeonjun first launched his solo project with the release of the EP "NO LABELS: PART 01" on Nov. 7, 2025 [1]. This debut followed a pre-listening party held on Nov. 6, 2025 [2], where the artist shared his excitement regarding the project. "I didn't know how long I've waited for this day. I'm so happy," Yeonjun said [2].

The momentum from his solo debut continued into the following year. On Oct. 3, 2026, Yeonjun earned his first solo music-show trophy on M Countdown for the track "GGUM" [3]. This win marked a significant achievement in the competitive South Korean music industry, validating his appeal as a solo act.

Beyond the domestic market, Yeonjun has entered the global sports arena. He is featured on the anthem for the 2026 World Baseball Classic titled "Make It Count" [4]. The track, which is scheduled for release on July 10, 2026 [4], features Yeonjun alongside U.S. artists Becky G and Myke Towers.

The collaboration is designed to promote the 2026 tournament and leverage the global reach of K-pop to attract a broader audience to the sport [4]. By partnering with established Latin and U.S. artists, the project bridges different musical genres, and cultural markets.

“"I didn't know how long I've waited for this day. I'm so happy."”

Yeonjun's trajectory from a group member to a solo trophy winner and a featured artist on a World Baseball Classic anthem demonstrates the 'multi-hyphenate' strategy common in modern K-pop. By diversifying his portfolio across solo discography and international sports marketing, he is reducing reliance on group brand equity and building a personal brand that can operate independently in the global music and entertainment markets.
