In the Japan Version of Itunes, the song, Butterfly by Kaera Kimura (aka Kaela Kimura), is currently the top song. According to Imdb Kaera is a “Top singer in Japan.” The video is a little strange, its kind of a world that seems like a kids popup book; it’s definitely different from other music videos. The song is OK, it isn’t very unique, but watch the video, you might like it!
