Artists with most all kills (in Melon - all kill is a concept only existing in there)

On surface, IU's all kill record at Melon, plus virtually all of her records in that digital seller, seem to be unassailable by anyone including BTS.
However, it is now all reset. of Me
When KakaoM surrendered to Spotify, the latter's records became supreme, and Melon just reverted to a regional chart relevant only in Korea. I-fans began to see Spotify as the true harbinger of popularity as far as digital is concerned.
So , while IU, who had gained some foreign following, did reasonably well in Spotify she no longer dominates the digitals as she can't compete against BTS and Blackpink and some others in Spotify.

No one thought the iron grip of Melon in Korea, good or bad (mostly bad), would break.
Melon had a market share of more than 50% and a lot of people, while not liking it, still stayed there because it was the biggest seller.
However, Spotify showed up. Spotify Korea was not that good, but a lot of people just went to the main spotify site, which no one could stop since virtually all Koreans can use proxy servers to connect from non-Korean IPs.
When Spotify removed all singers whose songs were distributed from KakaoM (which owns Melon), the companies complained .
The straw was the defection of PNation, Psy's company. It used to distribute its digitals through KakaoM, but because KakaoM was removed from spotify, PNation moved to another company , starting an exodus from KakaoM. If it went like this only IU would remain in KakaoM because it owns 40% of her company.
That led to an unconditional surrender of KakaoM to Spotify, which has made the Melon chart irrelevant almost overnight.
In my opinion, the breaking of Melon's power and the surrender of KakaoM to Spotify is the most influential news of KPop in 2021. That simply made all the digital monsters irrelevant, and basically ended the only-for-Korea balladists' chances.
The breaking of Melon's power will continue to have reverberations in Korean Pop for years; all the songs likely to be popular only to the K-O-R-E-A-N-S will simply be ignored by the i fans since they will refer to spotify and not refer to Mellon anymore. Kudos for SPotify for breaking the power of Melon/KakaoM.
