*Updated with how points work on Music Bank, how many wins the girls have atm, etc.
A bar graph showing the total points various KPOP artists have scored on “KBS Music Bank” since 2008 (when K-Chart began) up to July of this year. By far, SNSD has the most Music Bank K-Chart points in total. The bar graph shows that SNSD’s points are at least double the points artists, such as Big Bang, 2PM, and KARA have scored within the 2 years.
Up to this point, the girls have 21 K-Chart wins for the 5 songs,
Kissing You : 1
Gee : 11
Genie : 1
Oh : 6
Run Devil Run : 2
For those who are curious about how Music Bank K-Charts work, according to silis7noy2@soompi,
It’s bit complicated….If numbers give you a headache skip this and just look at a nice graph at the end
The 4 categories considered by Music Bank
Digital points (60%) – This is based on digital music sales from Melon, Mnet, Bugs, Dosirak and Soribada. Then mobiles sales are also added. Majority of mobile sales are from Nate ringtones sales.
Album points (10%) – This is based on sales numbers from Hanteo plus sales numbers submitted by offline music chain stores Hottracks and Synnara.
Broadcast count (20%) – the number of times the song was played on radio and TV. The points from this category is not as reliable as before, mainly because Mubank now considers broadcasts from only KBS and disregards SBS and MBC.
Viewer preference (10%) – This is voted by viewers. Viewers can register with the KBS research site to participate(Korean id needed). Then every week Mubank will select a sample from the registered members and allow them to vote. Viewers of all age/sex are evenly selected.
The detail of Music Bank ranking points is like this: First Music Bank starts with total kchart points of 200,000.
The digital sales category gets 120,000 kchart points (60%).
The album category gets 20,000 kchart points (10%).
The broadcast counts category gets 40,000 kchart points (20%)
The viewer pref category gets 20,000 kchart points (10%)
Now let’s look at how these kchart points are distributed to each song in each category. The process is very simple actually. For the digital sales category in order to simplify things only the top 100 selling songs are considered by Music Bank. Then the digital sales of all these 100 songs are examined, for example
song1 : 230,000 total digital sales this week
total digital sales 7,320,000 (total of all 100 songs above) (*of course all numbers here I just made up to illustrate, and some things are simplified for the purpose of this explanation)
How many kchart points does song1 get now?
Out of 7,320,000 total digital sales, song1 has sales of 230,000.
That is 3.142%
So song1 gets 3.142% of the 120,000 kchart pointed allotted to the digital sales category.
Thus song1’s kchart point for digital category is 3770 points.
And so on for other songs
And it works the same for other categories of album, broacast count, and viewer pref.
Now what is wrong with this Music Bank Kchart formula? The problem is that the way the points are distributed can allow one single album sales to dominate the kchart points. For example,
album1: 50,000 copies sold this week
album2: 3,000 copies
album100: 50 copies
Total album sales :80,000 copies this week
album1 alone sold 62.5% of the week’s total
album1’s kchart point will be 12,500 points out of 20,000 kchart points alloted for this category.
So unlike other categories, album sales can have these giant selling albums that can result in huge kchart points. See how tricky this formula is, the “10%” for album category makes it look like albums are worth only up to 10% but in fact that’s not the case as seen here. With kchart point like that 12,500 it is easy to win Music Bank even if the song is not popular at all and ranks very low on digital charts. We can obviously see there’s going to be controversy about this. Music Bank tried to fix this problem by adjusting the album category percentage from 15% to 10% but the problem is still there because the problem is still with the point distributing formula itself. Mathematically there are many ways to make a better formula for this case but well, we don’t need to get into that here
And as noted SNSD is not affected by these formula controversies because of their dominating power in all the categories. If Mubank lowers album category percentage even more, there will be no change in SNSD’s top Mubank power status. In fact during the Gee days Music Banks used only the digital sales for the kchart. And Gee won 9 weeks with that formula. Then people including some antis complained that Gee was able to win so many weeks because of the digital only formula so they demanded that Music Bank start including album points etc. So that was one of the reasons Music Bank changed the formula after Gee’s reign to include the 4 categories. And nothing really changed for SNSD they would still keep winning and winning, setting Music Bank records. And there have been numerous errors and glitches with sales data for SNSD especially compared to others. Even this week Nate misreported Hoot mobile sales and Ksones had to complain and correct it(it may still not be corrected). We probably lost a couple of Music Bank wins over the years because of these problems but Sones dont dwell over these little things^^
Whatever it may be the graph is believable, don’t you think? After all, during their “Gee” promotions, the girls won 9 consecutive wins for the hit song and were able to set a new record on Music Bank. Each win racked up thousands of points. I gotta admit, the girls are seriously impressive and I look forward to seeing the girls rack up more points with “Hoot” soon. Who else wants the girls win this week’s Music Bank K-Chart, especially when their album is topping the charts at the moment?
