lol XD I don't think you do - if you would, you woldn't know japanese music either XD
and me - I don't know a lot about other music too, I think. ^^; but sometimes, when I have time, I love to listen to a world music radio program about local music in countries all over the world [usually there is a lot of music from small musicians with their specific nice music, not the big stars ^^]
btw I just updated my journal with a concert from a czech musician Divokej Bill & Čechomor - I wondered how Gackt might react if I took him to such event ^^; XDDD I wonder if he would like it ^^
