APT. was arguably the strongest song which could plausibly called KPop, but it has dropped out from the top 10 of Billboard Hot 100.
Radio play has taken a big importance, and with Trump's return, the radio DJs are not too likely to play songs originating from Korea.
JK had done the impossible last year with Seven, which is likely to be the last KPop song to top Billboard Hot 100. If Roseanne Park, OBE, who is not a Korean, a native English speaker and combining forces with a singer who used to be famous , could not make it no one who could be considered Korean can do that.
Why Bang did not re-launch a tour in late 2021 - 2022 is only known to himself.
All these BTS solos eventually amounted to, I have to say, nothing , except JK's Seven.
Instead one of Agust D's solo songs was used by a rabid ultraconservative politician to drag all of them to the military.
JYP was smart not to allow Twice any solo songs till a number of years had passed.
It is rumored that BTS won't return till 2026 now, since no one knows how pop will progress in 2025. It will not be 2021 or 2022, for sure.
APT. had the best chance to top Hot 100 yet it peaked at #8.
If Rose can't do that who can?
History will record BTS not abandoning Korea as the most foolish business decision in the entire history of Pop.
