Even if the two kpop acts I actually like aren't on this top50 (Lee Jung Hyun and Uhm Jung Hwa, both are on the "almost" posts), it's a good series of texts to know some kpop artists that came way before BoA first stepped in Japan.
The thing is... those idols we get from kpop most of the time are mostly aimed to teenagers even in South Korea, and aren't really considered the best music produced on the country even by the natives...
