J-Pop J-pop Count Down

I just found something kind of interesting for those who like J-pop. It's a top 40 Japanese music count down, and they are based off of music charts from radio stations in Japan. I guess it's something that Anime Hard Core radio has had for a while, but I never noticed ><

well to open the station the link to it is off to the right side here : http://animehardcore.gamesquad.net/ahr/
