Somebody mentioned the fact which is perfectly true that for most of people Asian music is this chinese dialect ching chang etc
I'm in college and my classmates know that Ayu is my fav and they don't find it something strange. Maybe at first there were that face expressions you know... like i was a weirdo or sth
But I have really great school mates and sometimes they even ask me to let them listen to my mp3s xD (which is full of Ayu of course, and some Madonna).
