Doesnt even have to be hardcore classic country like from 60s or 70s. Modern country obviously has a lot of rock elements, in fact, i view modern country bands like Florida Georgia Line as the descendants of the 80s rock and hair metal bands that were killed off by grunge. I think a lot of us 80s rock fans found refuge in these "new wave bro country" bands and soloists like Luke Bryan. I havent paid attention to country since 2019 though so i dunno what's going on these days, once i found Kpop, i pretty much jettisoned all local music from my playlists lol.
But if Kpop has to move away from the colorpop/EDM trap of Twice and BP, i'd much rather see it bring over the power ballads and guitar driven anthems of this bro country than to see it go down the rehash RnB/hip hop/Latin road that has been done a trillion times already. There is a way too, we saw how lit some of those rock remixes of Kpop songs have been, i remember everyone was excited for the Fancy "Rock Remix" version a couple years ago at SBS Gayo 2019 i think.
I see where you’re coming from, but dance/choreo is such a pillar of the kpop industry. That just doesn’t mesh well with power ballads and hoedowns
