J-pop has a long and storied history which began with enka, but then K-pop borrows much of J-pop's aspects, styling, lyricism and business model which the Koreans then taken to severe lengths along with infusing their own aesthetics/image. Which is then the mostly aesthetic what much of so-called P-pop is now derived from K-pop, and that has become the selling point rather than the sophistication of the lyrics.
