Until last year, songs which were mostly or entirely in English were the trend in Korea.
To signify KPop's integration with global pop.
Even "Korean" songs had more than half of their lyrics in English.the
But then now Melon is coming back from dead to haunt KPop.
The #1s from Melon are all or mostly Korean songs
Love wins all - some English words, Korean composer/lyricist
Bam Yanggang - no English words, Korean composer/lyricist
Fate - some English words, namely "Iced americano" and the rap of Minnie, mostly Korean composer/lyricist with some foreign input
And, NWS' fate is also mostly Korean with some English words thrown in healbere and there.
And that is a Hybe act, although Pledis does have some independence.
Although Lee Jieun is no longer dominant digitally, her dream of undermining KPop seems to be finally bearing a toxic fruit after 14 years of struggle.
The drift of Koreans from global Kpop was only suppressed by BTS' foreign conquests, and without that, and with a singer who has been hostile to Kpop for her entire career now ruling as a Senior Singer and holding a veto power over Kpop, the Great Regression of KPop is now at full speed.
I personally think at this rate even if BTS returns in probably early 2026 there would be no ground to start anew as most music would be like only-for-Korea.
I feared this for a long time. And it is hitting KPop quite hard.
Only one kind of genre can survive, those songs which are palatable to the world or those who are only going to be relevant in Korea, and the wrong kind of music is winning.
