Mm, J-Pop... I don't listen to K-Pop too much...
My K-Pop listening is basically BoA's korean songs, but even then it's rare and I can hardly tell them apart (except for the really beautiful ones like We and Good-bye XD)~~
I think it's because I understand a little of japanese, and NO korean whatsoever XD it's easier to recognize songs. PLUS since I already listen to J-pop, I already know the artists that I like and need to look out for... I dunno much about the korean music industry haha XD and I'm too lazy to research about it

I know, I know... I'm lame...
