黛米·洛瓦托演唱版

Let it go, let it go

Can't hold it back anymore

Let it go, let it go

Turn away and slam the door

The snow glows white on the mountain tonight

Not a footprint to be seen.

A kingdom of isolation,

and it looks like I'm the Queen

The wind is howling like this swirling storm inside

Couldn't keep it in;

Heaven knows I've tried

Don't let them in,

don't let them see

Be the good girl you always have to be

Conceal, don't feel,

don't let them know

Well now they know

Let it go, let it go

Can't hold it back anymore

Let it go, let it go

Turn away and slam the door

And here I stand

And here I'll stay

Let it go, let it go

The cold never bothered me anyway

It's funny how some distance makes everything seem small

And the fears that once controlled me can't get to me at all

Up here in the cold thin air where I finally can breathe

I know I left a life behind but I'm too relieved to grieve

Let it go, let it go

Can't hold it back anymore

Let it go, let it go,

Turn my back and slam the door

And here I stand

And here I'll stay

Let it go, let it go

The cold never bothered me anyway

Standing - frozen in the life I've chosen

You won't find me, the past is still behind me

Buried in the snow

Let it go, let it go

Can't hold it back anymore

Let it go, let it go,

Turn my back and slam the door

And here I stand

And here I'll stay

Let it go, let it go

The cold never bothered me anyway

Let it go, let it go, and here I stand,

let it go, let it go. Let it go
