Yeah it was that piano track, I can't believe I didn't hear it for so long and then didn't realise it was part of the track.
I don't want to judge such a great musician, but I think I would like it better without the ticking. It really is a wonderful piece. Makes me think about the sorrow of war, and how mankind is forever trapped in a nightmare fighting his own shadow while surrounded by paradise; as this is how I see the deeper meaning in the game. Sigh...
Just a quick reply to admit my mistake, and explain that there will be no video now. Thanks for the replies.
