This is "Shadows" from Lindsey Stirling. I hope you enjoy.

The dark shadows in my head.
I am a fighter.
This moment I always dread.
I am now an igniter.

I must fight.
Fight them with all my heart.
Darkness to the light.
Time to start.

Fight my shadows with will.
I can't surrender now.
Time stands still.
I will not bow.

Bow to their abide.
It is my turn.
My turn to now side.
Before the shadows burn.

Side with the thought.
The thought of glee.
With the sword I brought.
I now will soon be free.

Silver, black, and pale blue.
In my armor I stand.
I won't let them be true.
Fight against the shadows hand.

A fight I will win.
A very strong magic.
With a small grin.
Emotions so tragic.

I will never bow.
Bow to their will.
I won't back down now.
Fight with time now still.

The shadows in my head.
The shadows in my mind.
The shadows of lead.
The shadows are never kind.

Fight them with light.
Fight with something happy.
I must fight.
Fight as they make me sappy.

I will lose.
No I won't.
I will choose.
Either choose or don't.

The shadows I fight.
I am a fighter.
Even through the night.
As I am a lighter.

The shadows I will beat.
I will never bow to their abide.
In cold or heat.
I will never hide.

A fight I made.
A fight I win.
With a sword of jade.
With a happy grin.

I battle the shadows now.
I fight my own battles.
Shadows never make me bow.
As the shadow rattles.

A fight with little sound.
A fight with joy.
I will make them hit the ground.
Like they are a toy.

They will lose.
I will soar.
They now choose.
As my fighter will roar.

The shadows lost.
I never bowed down.
With little cost.
I wear my new crown.
