On October 28, BTS's "Blood, Sweat, & Tears" beat IOI's "Very Very Very" and won first place. After the show, some viewers raised their concern about a potential error in the point calculation. Here are some of the comments from the IOI fans:
"Please recalculate the points."
"Fix the #1 win that IOI was robbed of."
"We want official feedback."
"KBS ignores viewers."
"Music Bank #1 win is weird."
"Music Bank #1 win is incorrect."
These concerns prompted 'Music Bank' to release the exact numbers and calculation. The following is the full statement from 'Music Bank':
"Hello, we are the production team of 'Music Bank.'
The October 28 live broadcast of 'Music Bank' and its 'K-Chart's 1st and 2nd place along with the points brought in a lot of questions and concerns, so we are here to reveal the details of the calculation method and points.
*Each category's percentage is not a reflective percentage but the percentage from the final, total points.
[Calculation for K-Chart points]
Digital airplay (online streaming) 65%, 130,000 points (online 117,000 points + mobile 13,000 points) + album sales 5%, 10,000 points + broadcasting appearance 20%, 40,000 points (TV 34,000 points + radio 6,000 points) + viewers' preference survey 10%, 20,000 points = total points 200,000 points
*numbers less than decimals are rounded up
[BTS - "Blood, Sweat & Tears]
Digital streaming: online 2535.4 points + mobile 138.1 points = 2673.5 points
Album sales: percentage in the market 41.52% (sales 89,308 albums) = 4152 points
Broadcast appearance: TV 685.88 points + radio 59.52 points = 745.40 points
Viewers' preference survey: out of a total survey of 6987, they earned 284. 4.1% of the answers, 813 points
Total points = 8384 points
[IOI - "Very Very Very"]
Digital streaming: online 4338 points + mobile 506 points = 4844 points
Album sales: percentage in the market 23.45% (sales 50,433 albums) = 2345 points
Broadcasting appearance: TV 588 points + radio 83 points = 671 points
Viewers' preference survey: excluded because it was conducted 1 week prior to the music release
Total points = 7860 points
We used the method above to determine that BTS ranks #1 and IOI ranks #2 on the K-Chart for the fourth week of October.
Thank you to all the viewers, and we will always try our best to give you prompt and accurate feedback to your concerns."
