if i heard a song i like in an ost i'd look it up (little bit o' Rain, Yb sound track, some ss501) same for japanese music, and i listened to Gackt and Buck Tick and some miyavi, but that was about it for asian music until fantastic baby came out and i saw it on kpop music monday which i watched even though i didnt listen to a whole lot of kpop at the time.
Big Bang lured me in, but the illness just keeps spreading. i can name more active kpop groups than i can american pop performers...by ALOT.
