It's fairly well known I am not a fan of power metal...in fact I despise it. One of my issues is that it sounds too positive and happy, like Christian music. In fact I think Christian metal is pretty bleak at times compared to power metal. If I had orcs or a dragon staring me down, I wouldn't be too cheery. Enough rambling. I wager you can take any power metal song, replace the word 'dragon' for 'Satan' and turn it into a full on Christian song.

Hammerfall - The Dragon Satan Lies Bleeding

(you can sing along with the music below) We Ride through the valley in thunder and rain the battle is raging, redeem this domain The Castle of Eden lies silent above darkness surrounded us, away we must go I look through the eyes of the world I see there's a Stranger among us. Awaiting a sign from above to conquer the power and the glory Enter the battle, our will to enchain bringing us forward, defeating the pain into the meeting with swords made of steel we're standing together the secret reveals I look through the eyes of the world I know who's the Stranger among us Awaiting a sign from above to conquer the power and the glory Come across to the Promised Land close your eyes, I will take your hand Through the river of steel we'll go When the dragon Satan lies bleeding (x2) Above the glory we'll carry on now the time has come to return back home The setting sun illuminates the dead the battlefield is shining red. Silent lies Eden on top of the moor we're fighting with honor protecting our Lord The last one survivor lies bleeding, I kneel into his heart I settle the steel I look through the eyes of the world there is no stranger among us. We march to the end of the world in search for the power and the glory Come across to the Promised Land close your eyes, I will take your hand Through the river of steel we'll go When the dragon Satan lies bleeding (x4)
