Ooh, I just can't stop listening Gackpoid's version of Cantarella. Vocaloids are cool but I like male's voice more than girls. In my point of view they sound more natural. Hatsune Miku is cool too but sometimes her voice doesn't fit at to the song she sings.

But no, thats wasn't my main thing. I was wondering... is Cantarella an original Vocaloid song (made just for Miku & Kaito) or is it from anime? I can't find any good answers xD
