[Estrofa]
            Em                     G                     C    D 
You're the sound of a song and I can't get you out of my head 
            Em                             G                         C    D 
You're the calm in the storm, you're the voice sayin', "Come back to bed"
[Pre-Estribillo]
       Em          G             C       D 
Maybe I'm just too tired to keep runnin' 
       Em           G         C 
Maybe you're what I never saw comin'
[Estribillo]
     Em          G 
Am I in your head 
                         C          D 
Half as often as you're on my mind? 
     Em              G 
If I don't make sense 
                            C 
Please, forgive me, I can't sleep at night 
    D         Em           G 
At least, not alone, not anymore 
             C                              D 
Not since I found what I never went lookin' for 
               Em         G 
And now you're in my head 
            C 
I must have lost my mind
[Estrofa]
           Em                           G                  C      D 
You're the scars on my skin, you're the past I don't wanna erase 
           Em                          G                       C      D 
You're the words on my lips that have left but I still seem to taste
[Pre-Estribillo]
      Em           G             C     D 
Maybe I'm just too tired to keep lyin' 
       Em          G          C 
Maybe you're all I ever wanted
[Estribillo]
     Em       G 
Am I in your head 
                        C          D 
Half as often as you're on my mind? 
      Em             G 
If I don't make sense 
                             C 
Please, forgive me, I can't sleep at night 
   D          Em           G 
At least, not alone, not anymore 
              C                              D 
Not since I found what I never went lookin' for 
               Em         G 
And now you're in my head 
              C 
I must have lost my mind
[Puente]
           Am                   C 
There's an empty space beside me 
                                       Em 
And I'll keep it that way until you're here 
           G 
I need you here 
            Am                       C 
There was a different face beside me 
  
But I sent her away 
                  Em       G 
'Cause you're not here, here
[Estribillo]
             C 
Am I in your head 
        D               Em 
Half as often as you're on my mind? 
      C 
If I don't make sense 
         D                    Em           D 
Please, forgive me, I can't sleep at night 
               C 
At least, not alone
