Hello, does anybody know the name of the song in this Youtube video?

Yes, I realize its a Saw video, and I know for a fact that its NOT Charlie's Music. I asked to the creator of the vid, and he said that it was by Audiomachine but did not give the name. I've searched Audiomachine's songs and have not found the song. I would greatly appreciate any help. Thanks in advance.

And if anyone can help with these vids as well (by the same guy as the vid above), that would be great:
