These are the chords I worked out from listening to it. They've been tested on 
both the piano and guitar and sound right. Sorry, I know on the guitar these are 
tricky to play, so I'll put some easier alternatives at the bottom. Enjoy! 

Bmaj                     F#maj
You know something I don't
                            G#m
It's not like you to be cold
                     Emaj              
Every night replayed over and over.
Bmaj                       F#maj
You say things that I don't
                      G#m  
You make me feel alone
                     Emaj
Every night replayed over and over.

Emaj
You say it's no concern
                    Bmaj      
And everything's alright.
Emaj
Sometimes we all get burnt
                    Bmaj      
And then we try to hide.
Emaj
And I know and I know and I know and I know we're wrong
                           Bmaj
We should have let things slide.

G#m                           Emaj
Cause when the night gets dark
                       Bmaj
And there's no way back
                   F#maj
I'll call your name but it's fading
F#maj
We're fading.

Bmaj                     F#maj
You know something I don't
                            G#m
It's not like you to be cold
                     Emaj        
Every night replayed over and over.
Bmaj                       F#maj
You say things that I don't

You make me feel alone
                     Emaj        
Every night replayed over and over.

Emaj
So many times you say
                       Bmaj
You're staying out tonight.
Emaj
I wish that I could just walk away
                         Bmaj
But I won't leave you behind.

G#m                           Emaj
Cause when the night gets dark
                       Bmaj
And there's no way back
                   F#maj
I'll call your name but it's fading
F#maj
We're fading.

Bmaj                     F#maj

You make me feel alone
                     Emaj        
Every night replayed over and over.

F#maj                         Bmaj
Well I won't look back no more
                      G#m
Just like I did before
                           Emaj
Always thinking that it's gonna be alright.
F#maj                    Bmaj
And I'm gonna start again
                         G#m
This time I won't pretend
                        Emaj
That you're coming back into my life.

Bmaj                     F#maj

Every night replayed over and over.

Bmaj                       F#maj

                      G#m  
You make me feel alone
                     Emaj        
Every night replayed over and over.
