Hmmmm I started listening to J-pop (thanks to the endings of mangas like Inuyasha, Rurouni Kenshin etc...).
I was really into: M-flo, Ayumi Hamasaki, Utada Hikaru (I saw her in concert in London
), Chemistry, Boa (in japanese too because like ucimae I first discovered her as a Jpop artist), akeboshi, some endings/openings from Bleach and Naruto :p ("We are fighting DREAMERS!!!")
Then I guess I got fed up, seeing that M-flo was about to stop their "M-flo loves" collaboration era, and most of those singers had reached their popularity peak, I needed something more...
Enter Kpop ^^: Big Bang, 2NE1, Hyori, Son dambi, super junior and some korean variety shows with subs.
Then I discovered AMAZING Korean groups (they're not as popular as the idols but their music is GREAT): Epik High, Dynamic Duo, Clazziquai Project, Winterplay, House rulez. ^^
