I don't know... I just get a different feeling listening to the Japanese language than I do listening to English. I started out with anime music too, (ugh) then I discovered Ayu and just fell in love with everything, it's just unexplainable. Now I really have come to like a lot of Japanese music, new and old, through many different genres. I'm currently really into B'z, Yutaka Ozaki, Love Pyschedelico, and Southern All Stars. But Ayu, will probably always be #1 for me, at least I'd like to hope so...
