Em 
You got my heart on a string
Em                     G                 Asus4
You want me back again and you know I'll do anything
Em
Just when I thought I was free
Knock, knock, the door is locked
G                   D
But you still got a key

C                     G         D
All too familiar, the moment it shows up
C                           B7
Now everything I know seems to fly

Em
My oh my
                            C
You're getting under my skin
           G                            D
Don't know why I'm always letting you in
            Em                        C
Just when I got my life together again,
                           G 
Here you are standing there 
                     D
Tell me why I should try-y-y
      Em     C
My oh my-y-y
      G      D
My oh my-y-y
      Em     C
My oh my-y-y
      G      D
My oh my-y-y

Em
You got me under a spell
                                  G                  D 
You look like heaven, oh, but you put me through hell
Em 
God knows there's nothing to gain 
     Em                           Em*                  D
Well who am I to deny, we're both playing the same game

C                       G                D
All too familiar, the moment it blows up
C                              B7
Now everything I know seems to fly


Em
My oh my
                            C
You're getting under my skin
           G                            D
Don't know why I'm always letting you in
            Em                        C
Just when I got my life together again,
                           G 
Here you are standing there 
                     D
Tell me why I should try-y-y
      Em     C
My oh my-y-y
      G      D
My oh my-y-y
      Em     C
My oh my-y-y
      G      D
My oh my-y-y

Am                         D
And I know that you're no good for me
G                         Em
 And it makes no sense at all
Am                   D
 Still I keep coming back for more
C                             B7 
 'Cause I'm addicted to your call

(This is the part she drums with her finger,
 playing E and A strings)

Am                                         
I know you ain't no good for me            
And all the lies and the lines you fed to me      
Em                                               
The way you kept coming back for me                
Like the last breath left of the air I need   
                                                    
Em
I know you ain't no good for me
And all the lies and the lines you fed to me
Em
The way you kept coming back for me 
Like the last breath left of the air I need


Em
My oh my
                            C
You're getting under my skin
           G                            D
Don't know why I'm always letting you in
            Em                        C
Just when I got my life together again,
                           G 
Here you are standing there 
                     D
Tell me why I should try-y-y
      Em     C
My oh my-y-y
      G      D
My oh my-y-y
      Em     C
My oh my-y-y
      G      D
My oh my-y-y
 
      Em     C  G  D
My oh my-y-y
      Em     C  G  D
My oh my-y-y


(She drums with her finger again,
 she ends the song playing the E and A string)
Em
My oh my 
I know you ain't no good for me
And all the lies and the lines you fed to me.
