TVXQ's U-KNOW Yunho Goes Solo Again: "Time's Tickin'" and Why Veteran Idols Keep Releasing Music

23 years since debut. Still touring. Still releasing solo music that tops charts in 18 countries on day one.
One of K-POP's original superstars is back with a solo single today — here's why TVXQ's U-KNOW Yunho still matters to a genre he helped build.
Quick Answer

U-KNOW Yunho, one half of the legendary duo TVXQ, releases his first single album "Time's Tickin'" on July 20, 2026 at 6 PM KST. The release features the title track of the same name plus a B-side, "An Ordinary Story," and Yunho personally co-wrote the lyrics. It's a contemporary pop dance track about staying determined despite the passage of time — a fitting theme for an artist over two decades into his career and still actively touring and releasing new music.

Who Is U-KNOW Yunho?

Yunho (real name Jung Yun-ho) is one half of TVXQ, one of the foundational groups of K-POP's second generation. TVXQ debuted as a five-member group in 2003 under SM Entertainment; following the departures of Jaejoong, Yoochun, and Junsu in 2010, the group continued on as a duo consisting of Yunho and Changmin. More than two decades later, TVXQ remains active, and both members have built substantial solo careers alongside the group's ongoing activities — Yunho debuted solo in 2019 with the mini album "True Colors" and has released steadily ever since.

What's on "Time's Tickin'"

"Time's Tickin'" drops July 20 at 6 PM KST as Yunho's first single album, containing the title track of the same name plus a B-side, "An Ordinary Story." According to allkpop, "Time's Tickin'" is a contemporary pop dance track built around an upbeat rhythm that mimics the sound of a ticking clock, with a powerful chorus amplifying its energy. Yunho personally participated in writing the lyrics, using the song to express determination and unchanging aspirations despite the passage of time — a theme that reads directly as a statement about his own two-decade career rather than a generic pop lyric.

The comeback was announced with a cinematic intro film rather than a standard teaser, continuing Yunho's pattern of treating his solo releases as concept-driven short films rather than simple promotional clips.

Yunho's Solo Career So Far

Yunho's solo catalog is smaller than some of his peers, but each release tends to be built around a distinct concept rather than following trend cycles. His 2021 mini album "NOIR" is the clearest example: a six-track "concept album" where every song had its own short film and genre inspiration, ranging from the noir-gangster "Thank U" to the lighter, dance-driven "Eeny Meeny," which featured Red Velvet's Seulgi. "NOIR" debuted at No. 1 on Korea's Circle Album Chart and topped iTunes charts in 18 countries on release day.

Why Veteran Idols Still Release Solo Music

If you're newer to K-POP, it can be a little confusing why an artist more than two decades into their career keeps releasing new solo material instead of settling into a legacy-act role. In practice, solo work for long-tenured idols like Yunho tends to serve a different purpose than it does for younger acts — it's less about breaking into the industry and more about creative range, sustaining relevance between group promotions, and giving devoted longtime fans a reason to stay engaged year-round rather than only during group comebacks. Yunho pairing this release with an active solo tour follows that same logic: the single and the live shows reinforce each other rather than competing for attention.

Pro Tip

If "Time's Tickin'" is your first real exposure to Yunho's solo work, go back to "NOIR" next — it's the release that best shows his range, since every track on it was built as its own distinct short film and genre experiment rather than a uniform concept.
