I recently watched anime series 'Peacemaker Kurogane.' I love the OP. Can somebody lend me the lyric of it? or generously where can I download the music? Please... Can't get the music out of my head.

That'll be the closest thing I can find at the moment. It has the music and the lyrics (no translations though and the music just plays on windows media or a similar program.)
