Even though I didn't like the movie that much, I do have to give credit to Whoever made this theme song. In my opinion. This is what military marching music would be like.
John Henry Irons, a gifted inventor, kind hearted person, caring citizen, and a bold US soldier, has got balls made of steel. After his life is saved by the Man of Steel, none other than Superman himself, whom seemingly sacrificed his life to protect him among many others, killed and no where to be seen, John with his heart full of compassion and raging flames; made a bold decision, to commemorate in honor of the great Man who saved his life, forged the irons of justice, made of seemingly tough and impenetrable steel armour that shines on the depths of crime and evil, giving light to those needed, just like his hero did for them. With his mighty mortal strength, he protects the innocents , as another selfless savior, regardless of gender and ethnicity, young or old, his Hammer of great Steel strikes through the hearts of crime. Thus, he continues this legacy, though exhausted and grave, he walks out of the flames of sorrow and despair, rising from ashes with hope, as the Armoured knight, as Steel!
