Six shows, six number ones, every week: how Korean music chart wins are actually scored

Korea runs six weekly music shows. They split the days of the week between them, and each one crowns a winner.

Which means most weeks produce six number ones.

There cannot be six most-popular songs in the same seven days. So those six wins are not a popularity ranking — they are six different formulas each returning its own answer. And every one of those formulas is published.

At a glance

Read the streaming column downwards and it swings from 60% to 35% — nearly double. Voting swings from 10% to 40%, a factor of four.

But there is something the table does not show. Add the rows across and the totals don't match. Music Bank and Show Champion come to 100. Music Core and M Countdown reach 110, Inkigayo 115, The Show 120. The overflow is almost always live voting during the broadcast — a base of 100% is settled in advance, then a pool of votes that can still move is stacked on top. The result is designed to stay overturnable until the final minutes, because the programme needs that scene.

A show that weights streaming at 60% crowns a different song than one that weights it at 35%

Music Bank scores out of 200,000 points, and 120,000 of them are digital streaming, pooled from Melon, Genie, FLO, VIBE and Bugs and converted into a share. The remaining 80,000 are split between broadcast frequency, fan voting, physical albums and social.

In that structure there is essentially one route to the top. The song has to be played a lot inside Korea. However organised a fandom is, voting is 10% and albums are 5%. Maxing out both gets you 15%, which rarely closes a streaming gap.

Show Champion sits at the opposite end: streaming 35%, voting 20%, albums 15%, broadcast 20%. More than half the sheet lives outside the streaming charts. A song can place modestly on Korean streaming and still win if the fandom is large and coordinated.

So two shows crowning different songs in the same week is not an error. They are answering different questions. Music Bank is closer to "what did Korea play most this week," and Show Champion is closer to "whose fandom moved most efficiently this week."

Some points only exist if you turn up

The broadcast column is the one international fans almost never see.

Music Bank's 20% counts how often the song aired across KBS channels — television, radio and digital. Show Champion's 20% works differently: it is scored on the teams who appeared on that week's episode.

If you are not on the stage, those 20 points are not points you lost. They never existed for you.

That reframes the shortlist. On 29 July 2026 a special episode of Show Champion listed five nominees — fromis_9 with 〈Vitamin ME〉, LUN8 with 〈SNEAKERS〉, WONHO with 〈Don't Wake Me Up!〉, TVXQ's Yunho with 〈Time's Tickin〉, and Jennie with 〈Less than a Lover〉. fromis_9 won.

Judged on name recognition alone the result looks off. Put the scoring sheet beside it and it stops looking off. Being nominated and being able to compete are two different things, and much of the gap comes down to who was physically in that studio. This is why rookie and mid-tier groups grind through the music show circuit — showing up is the score.

The sheet does not measure the song. It measures the promotion.

A song that wins three times gets struck from the ballot

There is another layer. Show Champion filters the shortlist itself. Remakes, pre-release singles, drama soundtracks, trot, songs failing broadcast review — and any song that has already taken three career wins — are excluded from nomination.

That last one matters. If a song is dominant enough to win three weeks, it is absent from the ballot in week four. The trophy goes to whoever was second.

The rule exists to keep the programme watchable, not to distort the ranking; eight consecutive weeks of the same winner gives nobody a reason to tune in. But the side effect is structural: it makes "number one equals the best song that week" impossible to read literally. The song that won three weeks was probably still ahead in week four. It simply is not on the list.

Sometimes what an index excludes tells you more than what it counts. Korean drama ratings do the same thing — Netflix titles have no seat in the ratings table at all.

In ten years the judges disappeared and the polling booths multiplied

But there is no point memorising the table above. Within a few years half of it will be wrong.

Around 2016 the same shows scored quite differently. Music Bank put streaming at 65%, and broadcast frequency at 20% mattered so much that fans nicknamed it "Broadcast-Point Bank." Show Champion carried an expert preference score worth 15% that no longer exists. The Show leaned heavily on Chinese fan activity, filling much of its pre-broadcast score with views from a Chinese video platform.

The direction reads as a single sentence. Experts were removed and fan voting took the space. Show Champion's 15% expert score vanished and a 20% global fan vote arrived. The Show scrapped broadcast points entirely and moved that weight into voting too, reaching a combined 40% across advance and live ballots.

You can call that democratisation, or you can call it a ranking drifting from music toward mobilisation. Either reading leads to the same practical conclusion: a fandom account's scoring guide goes half-obsolete within about a year.

When the counting window misses release day, week one barely counts

The counting window moves results as much as the weights do. Show Champion uses streaming, album and SNS figures from the Monday to Sunday preceding the episode; advance voting opens the previous Friday at 8pm and closes at 2:59pm on the Monday of broadcast week. Only broadcast points are scored on the day.

So a group releasing on a Wednesday gets four days counted that week. A Thursday or Friday release gets fewer. Part of the reason K-pop comebacks cluster at 6pm on Mondays and Tuesdays is this calendar.

It also explains a scene that repeats constantly: the same song sweeping several shows in its second week. The song did not suddenly improve. That was simply the first week a full seven days made it into the count.

Which of your clicks actually become points

This is the question international fans ask most, and splitting the table by row gives a reasonably clear answer.

Counts regardless of where you are — YouTube music video views. That is largely what the SNS and video columns measure, and it is a worldwide total with no regional weighting. Worth knowing what that figure actually represents, though: in a world where the fastest run to 100 million views took 21 hours, view counts track simultaneous mobilisation more than popularity.

Usually counts — physical albums. Copies bought and shipped internationally are frequently picked up by Hanteo and Circle Chart. The dividing line is not the country but the retailer: whether the shop reports into the tracked distribution network. Two buyers paying the same price for the same album can end up with one purchase scored and the other not.

Depends on where you are — streaming. It is the largest single item on almost every sheet, and it is measured on Korean streaming services. The global services most listeners outside Korea actually use do not feed those numbers directly. The 40–60% column is the one that is hardest for an overseas fan to reach.

Advance voting varies by app. Show Champion uses Idol Champ, The Show uses BIGC. Sign-up is generally open, but some routes still require a Korean phone verification.

Almost never counts — broadcast points. Nothing a fan does moves that number.

What this means where you are

Three practical notes follow from that.

First, when you read a fandom account's voting guide, check which show and which year it describes. Weightings are revised regularly. The Show removed broadcast points entirely in 2026 and doubled physical albums from 10% to 20%. A guide written in 2025 is half wrong from that moment on.

Second, aim at week two rather than comeback week. Because of the counting window, a release week usually contributes only a few days. Streaming or buying concentrated in the second week converts into points more efficiently.

Third, read the show's name alongside the win. Six of them land every week, so a "they got number one" post without the programme attached is a sentence with half the information missing.

And once you have read all of these sheets, an odd gap is left over. None of the six counts international streaming properly, yet a substantial share of K-pop revenue already comes from outside Korea. The market being measured and the market paying have drifted apart. The categories invented to close that gap carry names like "global fan vote" and "fan engagement score" — and what both of them measure is not listening. It is loyalty.
