I've written a few new songs. None of them are parodies, but people say they're pretty good.
I'm going to post my favorite.
I've already recorded this one (Made a demo tape, going to go send it off to the record companies on the off chance someone listens to it):

Gears of War

(Intro - 28 Measure Rest)
(Verse 1)
As the sun goes to bed and dusk turns into night
We load up all our gear and ride into the fight
Getting ready for battle, put our weapons on our back
Preparing for an epic fight, getting back on track
The enemy army lines up, forming up their ranks
Visible on the distant horizon is a battalion of tanks
We try to fight but we cannot win, soldiers fall at the door
These are the gears - The Gears of War
(Chorus)
Heavy artillery, precision sniper rifles, nuclear warfare
Self-guided robots, advanced computer systems, let me out of this nightmare
These are the gears of war
(2 Measure Rest)
These are the gears of war
(2 Measure rest)
These are the gears - GEARS OF WAR!
(Verse 2)
(8 measures - Random Screaming)
(43 Measure rest)
The front lines have opened fire, hell is everywhere
Bombers pass overhead only to be shot out of the air
Half the troops are gone, panic begins to spread
Before this nightmarish day is over we'll all be dead
A jet crashes and wipes out the front ranks
More and more men are falling victim to the enemy tanks
The water is a blood red, bodies litter the field
We begin to cower in fear and pain, our fate is sealed
(Chorus 2)
Heavy artillery, precision sniper rifles, nuclear warfare
Self-guided robots, advanced computer systems, let me out of this nightmare
These are the gears of war
(2 Measure Rest)
These are the gears of war
(2 Measure rest)
These are the gears of war
(Chorus 3)
Heavy artillery, precision sniper rifles, nuclear warfare
Self-guided robots, advanced computer systems, let me out of this nightmare
These are the gears of war
(2 Measure Rest)
These are the gears of war
(2 Measure rest)
These are the gears - GEARS OF WAR!
(4 measure rest)
(Verse 3)
Our men are falling back, the battle has been lost
We will have to retreat during the cold winter frost
Let's not forget what we are fighting for
These are the gears - The gears of war
Chorus 4)
Heavy artillery, precision sniper rifles, nuclear warfare
Self-guided robots, advanced computer systems, let me out of this nightmare
These are the gears of war
(2 Measure Rest)
These are the gears of war
(2 Measure rest)
These are the gears - GEARS OF WAR!
(4 measures - Laughter)
(Outro - 24 measure rest)
