Leona Lewis - Heartbeat chords

Okay, so I know this is not the original chords, but I think they work pretty well anyway. 

Not so sure about the Em in the pre-chorus, so let me know if you have any better suggestions? :)

Enjoy!


Intro:

G Am C D

Verse 1:
              G
If I could've laid low
           Am
I would be creeping round the streets
         C
Avoiding all the busy main roads
            D
And keep an ounce of dignity

              G
If I could've stayed home
           Am
I would've slept through everything
            C
Turn off my phone and read the silence
            D
Stay in the comfort zone of me

Pre-Chorus:
      Em
Cause nobody lies in there and
Am
Nobody's heart gets broken
C
Nobody cries in there
    D
But I ain't going in

Chorus:
       G
When I don't speak
                Am
Weak and hollow heartbeats
                C
Leaking from my heartsick
              D
Body sells me out, sells me out
     G
So I keep this
                  Am
Cheap and shallow heartbeat
            C
Under my control
                          D
And you will never see me weak

And you will never hear my
G
Heartbeat (Never hear my)
Am
Heartbeat (Never hear my)
C
Heartbeat (Never hear my)
D
Heartbeat (Beat)

Verse 2:
           G
If I never met you
        Am
I would busy with my life
         C
Going to work and still be happy
           D
I would be sleeping through the night
[ Tab from: http://www.guitaretab.com/l/leona-lewis/217968.html ]
                  G
And if I could forget you
           Am
I would go back and look for parts
             C
For patching up my broken heart
            D
And I would shut my aching eyes

Pre-chorus:
      Em
Cause nobody shouts in there and
Am
Nobody wants forgiveness
C
Nobody doubts in there
    D
But I ain't giving in

Chorus:
       G
When I don't speak
                Am
Weak and hollow heartbeats
                C
Leaking from my heartsick
              D
Body sells me out, sells me out
     G
So I keep this
                  Am
Cheap and shallow heartbeat
            C
Under my control
                          D
And you will never see me weak

You will never hear my
G
Heartbeat (Never hear my)
Am
Heartbeat (Never hear my)
C
Heartbeat (Never hear my)
D
Heartbeat (Beat)(Beat)(Beat)

Bridge:
Am             C        
  If I keep it down
     G 
just focus
D
I'm invisible
Am                       C
  Cause when there is no sound
             G
I know where I belong.
D
I will be okay
 
Chorus:
       G
When I don't speak 
                Am
weak and hollow heartbeats
                C
Leaking from my heartsick 
              D
body sells me out, sells me out (no, no, no)
     G
So I keep this 
                 Am
weak and shallow heartbeat
             C
under my control (under my control)
                          D
And you will never see me weak 

you will never hear my
G
Heartbeat (never hear my)
Am
Heartbeat (never hear my)
C
Heartbeat (never hear my)
D
Heartbeat (beat)(beat)
