The idea is every time an artist charted on top 100, they get a score depend on the rank:
- The score is calculated as rank ^ -0.8. Rank 1 will have score of 1.0, rank 2 has score 0.57, rank 3 has score 0.42 and so on. It's better compared to other simple alternatives:
- Linear, for example 101 - rank. So #1 = 100, #2 = 99, #3 = 97, etc. High ranks lost its significance, an artist with #49 and #50 will have higher total score than a single #1,
- 1 / rank: too top-heavy. a #2 has 5x higher score than a #10, #3 is 3.3x higher than #10. But in reality the differences between #2 / #3 vs #10 are not that big. With this formula the differences are only 3.6x / 2.6x,
- rank ^ -0.8 is actually the least top-heavy function still satisfies #1 > #2 + #3 (1 > 0.57 + 0.42).
- If the track is a collab then split the score to all participants.
I'm using official weekly chart data from Melon (https://www.melon.com/chart/search/index.htm). Here is top 10 overall artist since 2005 to 07/2025:
| Rank | Artist | Translated | Total score |
| 1 | 아이유 | IU | 259.75 |
| 2 | 방탄소년단 | BTS | 171.08 |
| 3 | BIGBANG (빅뱅) | Big Bang | 161.17 |
| 4 | NewJeans | NewJeans | 126.44 |
| 5 | IVE (아이브) | IVE | 100.69 |
| 6 | 다비치 | Davichi | 99.76 |
| 7 | SG 워너비 | SG Wannabe | 96.84 |
| 8 | aespa | aespa | 92.75 |
| 9 | AKMU (악뮤) | Akmu | 88.61 |
| 10 | 볼빨간사춘기 | Bolbbalgan4 | 78.35 |
* Bolbbalgan4 was originally a duo, but became solo since 2020
Interpretation: IU has total score of 259.75 mean she has equivalently 259 weeks at #1, or 454 weeks at #2.

Personally I find ranking all artists is fun, but it's also very hard. The chart was being reformed many times, a #1 in 2015 is different than a #1 today. 4th generation girl groups benefit from it the most, they break all of the records 15-16 years go. But does that mean they dominate the chart more than earlier artists? We don't know.
