There is a market today for the type of music you described, but you have to go to Korea to hear it.
KBS World TV is a Korean broadcasting network that features live performances of popular Korean singers on the show “Immortal Songs2”. This is not what’s known as K-Pop, it’s more along the lines of “standards” and similar in genre to what The Carpenters did.
Although the language is Korean, the music is very Western feeling and not unfamiliar like Chinese or Japanese music.
The 2 ladies performing in the link below are the duo “Davichi”. Although they’ve performed many times on the show, the first link is to “Do You Know” and is subtitled.
The second is “The Maze of Love”.
IMO,this is truly singing, not screeching.

Very nice. Thanks. I knew nothing about this trend. I’m guessing you mean South Korea. I don’t see Kim Jong Un stepping up to the mike to karaoke the song “People” as sung by Barbara Streisand. Maybe he’d do that song ‘I’m So Ronely’, as heard in the animation movie Team America.
