Why D.O.'s 'Popcorn' Is Charting Again Two Years Later — The Science Behind K-Pop's Reverse-Charting Phenomenon

Two years after its release, a song about the feeling of falling in love — written by an EXO vocalist, tucked inside a mini-album called Blossom — is climbing every major streaming chart in South Korea simultaneously. D.O.'s "Popcorn" has reached Melon daily No. 27, FLO No. 5, Bugs No. 4, and Genie No. 24, all without a new release, a comeback stage, or a single promotional post from the artist.

What triggered it? A story about a wedding. And that story, in turn, reveals something important about how K-pop audiences listen — and how a song can find entirely new life long after its chart debut.

The Catalyst: A Story That Moved Fans

The revival traces directly to a revelation on the variety program Halmyeongsu. D.O. shared on air that he had planned to perform "Popcorn" as a wedding congratulatory song for his close friend, actor Kim Woo-bin, at Kim's December 2025 ceremony with actress Shin Min-ah. The catch: D.O. was unable to attend, as EXO's schedule at the 2025 Melon Music Awards fell on the same date.

That story — of a song intended as a gift, withheld by circumstance — spread immediately across fan communities and social media. Listeners went back to "Popcorn" not just to hear it again, but to hear it the way D.O. had imagined sharing it. Streams climbed sharply starting April 2, moving from Melon No. 83 to No. 27 within five days. The velocity was consistent across platforms, which is a signature of genuine organic listening rather than coordinated streaming campaigns.

The cross-platform consistency is what distinguishes this revival from noise. When a song climbs on Melon but not FLO, it often indicates a platform-specific boost. "Popcorn" climbing simultaneously across all four major Korean services points to genuine listener interest driving the numbers.

What Makes "Popcorn" Work

"Popcorn" was released on April 30, 2024 as part of D.O.'s third mini-album Blossom. The song uses an extended metaphor — the feeling of falling in love compared to popcorn kernels bursting under heat — as its central image. It is built around a light, whistling sound design, a brisk tempo, and D.O.'s characteristic clean vocal tone, which sits somewhere between warmth and precision.

That sound profile turns out to be well-matched to two specific contexts: spring in South Korea, and weddings. The song's emotional register — giddy, slightly nervous, overwhelmingly sweet — makes it an intuitive fit for both, which is why fans immediately connected D.O.'s unrealized performance plan with the track itself. The song already sounded like something you would sing to celebrate someone you loved. The variety show story simply gave that feeling a specific, real-world frame.

Fan comments during the revival week included observations like "the song is so refreshing and exciting" and "listening to this makes me feel happy" — language that points to emotional recall rather than discovery. For many listeners, the chart climb was not about hearing something new. It was about revisiting something already loved, now carrying additional emotional weight.

The Yeokjuhaeng Tradition — K-Pop's Reverse-Charting Playbook

The Korean music industry has a specific term for what is happening to "Popcorn": yeokjuhaeng (역주행), or reverse-charting. The phenomenon is well-documented and follows recognizable patterns. A song underperforms or goes unnoticed at release, then a specific trigger — a viral video, a variety show moment, a celebrity connection — brings it back into circulation.

The classic cases have become K-pop industry lore. EXID's "Up & Down" (2014) was revived by a single viral fan-filmed fancam that circulated on social media — from near-obscurity to a full chart comeback months after release. Brave Girls' "Rollin'" followed an even more dramatic arc: released in 2017, it spent nearly four years largely forgotten before a YouTube compilation of military performance clips launched it to No. 1 in 2021. DAY6's "You Were Beautiful" has charted multiple separate times across different years, each triggered by a different cultural moment.

What these revivals share is not just a trigger event — it is a song that was always capable of connecting broadly, but needed a distribution mechanism. The fancam, the YouTube compilation, the variety show story — each served as a recommendation engine more powerful than any promotional campaign. The song did not change. The pathway to it did.

D.O.'s Solo Career and What This Revival Means

D.O. — born Doh Kyung-soo — debuted with EXO in 2012 under SM Entertainment and has since built one of the more distinctive dual careers in Korean entertainment, balancing a respected acting filmography with solo music releases. His solo debut, Empathy (2021), sold over 380,000 copies and earned KMCA Platinum certification. He followed with Expectation (2023) and Blossom (2024), which contained "Popcorn."

What the "Popcorn" revival demonstrates is the durability of that audience — and the depth of goodwill that comes with it. D.O.'s fanbase did not just stream the song; they explained it to others and created the conditions for broader discovery. The chart climb was as much a collective storytelling act as a listening event. Fans were not just playing the track — they were sharing the story of why it mattered.

For D.O., that dynamic represents a particular kind of career asset. Songs that accumulate new context over time — that can be heard differently depending on what the listener knows — tend to stay in rotation longer than tracks that exhaust their meaning at release. "Popcorn" has now been heard as a debut single, a spring song, and as something a close friend wished he could have sung at a wedding. Each frame adds to its resonance without diminishing the others.

What Comes Next

The immediate trajectory of "Popcorn" will likely plateau once the story's news cycle fades. Reverse-charting events are typically bounded: the trigger event creates a spike, the spike drives a few weeks of elevated streaming, and then the song settles at a higher baseline than before. That baseline matters. "Popcorn" will now be easier to discover for new listeners, better positioned in algorithmic playlists, and more likely to resurface again in future spring seasons.

The broader implication for the K-pop industry is what it always is when a reverse-charting event captures attention: catalog matters. Songs released years ago are not inert. They are waiting for the right moment, the right story, the right pathway back to listeners. For D.O., a 2024 mini-album track has just become, in April 2026, one of the most-streamed songs in South Korea. That is the kind of longevity that promotional campaigns cannot manufacture — but good songwriting, and a compelling story, absolutely can.
