附：《Fight of your life》完整英文版歌词

There is a fire in your soul

A power no one knows

Your Fate is still untold

So reach out and take control

They cant divide us

We won’t be denied

We survive...

This is the fight of your life

Strike with all of your might

Shine like a blinding light

This is the fight of your life

Break the chains and rise

Fly till you break through the sky

This is the fight of your life

We won't fall no we won't turn back

No one to follow we've made our path

All we've lost now it's in the past

We can rise as one at last

They cant divide us

We won’t be denied

We survive...

This is the fight of your life

Strike with all of your might

Shine like a blinding light

This is the fight of your life

Break the chains and rise

Fly till you break through the sky

This is the fight of your life

Never gonna stop fighting

You're never gonna take us down

Soon we're gonna steal the throne cuz it's our time now

We strike like a bolt of lightning

Our strength gonna shake the ground

We break through your gates and armor

We ain’t stoppin’ till we hold the crown

This is the fight of your life

Strike with all of your might

Shine like a blinding light

This is the fight of your life

Break the chains and rise

Fly till you break through the sky

This is the fight of your life
