Hello everyone, I hope I am in the right section.

Does anyone know whether this song: StarMan!!! ／ 天月-あまつき-【オリジナル】 by the singer Amatsuki ever got released?

I struggle to find a MP3 version of it. As far as I know, there seem to be a one off Music Video? Would anyone know? I would love to able to listen off-line on my iPod~ Thank you in advance.
