I noticed there were only tabs for Demi Lovato's version of this song, so here's the 
movie version. :)

Capo 1st fret

Em C D Am Em C D 
Am A

    Em                      C
The snow glows white on the mountain tonight
      D               Am
Not a footprint to be seen
  Em            C
A kingdom of isolation
       D                  Am   A  Em
And it looks like I'm the queen
            C                 D                Am   Em
The wind is howling like this swirling storm inside
                 C                  A        D
Couldn't keep it in; Heaven knows I've tried
                                     C
Don't let them in, don't let them see
                                      D
Be the good girl you always have to be
                                    C
Conceal, don't feel, don't let them know
     C
Well now they know
       G          D
Let it go, let it go
      Em               C
Can't hold it back anymore
       G          D
Let it go, let it go
       Em              C
Turn away and slam the door
G        D                Em        C
I don't care what they're going to say
        Em         Bb      C                             
G D
Let the storm rage on, the cold never bothered me anyway
Em                    C
It's funny how some distance
      D               Am
Makes everything seem small
        Em                 D
And the fears that once controlled me
      C            A   D
Can't get to me at all
                            C
It's time to see what I can do
                             D
To test the limits and break through
                                 C
No right, no wrong, no rules for me, I'm free
       G          D
Let it go, let it go
     Em                    C
I am one with the wind and sky
       G          D
Let it go, let it go
        Em          C
You'll never see me cry
G       D        Em        C
Here I stand and here I'll stay
        Em         Bb  C
Let the storm rage on
C
My power flurries through the air into the ground
C
My soul is spiraling in frozen fractals all around
Am                                            Em
And one thought crystalizes like an icy blast
           C
I'm never going back
    D              Am
The past is in the past
       G          D
Let it go, let it go
         Em                     C
And I'll rise like the break of dawn
       G          D
Let it go, let it go
     Em              C
That perfect girl is gone
G      D            Em       C
Here I stand in the light of day
        Em         Bb
Let the storm rage on
    C
The cold never bothered me anyway
