One can become the most streamed artist in the world and yet not become the most streamed artist in Korea.
Right now BTS has about 23.3 billion streams while Drake, the #1, has 44.4bil.
However Drake is slowing down and BTS still has some years remaining.
So it is remotedly possible for BTS to become the most streamed artist of all time.
But,
in Korea,
the most streamed artist of all time is someone born on May 16, 1993.
While the 2:1 gap in mid 2019 chart has been remedied a lot, it is not too likely that BTS is to beat the record set by a singer who contributed so little to KPop's Advancement to the rest of the world.
Nothing is more ironical than that.
