Key: C
Introduction: Dm C Dm C
Dm C Dm C Dm C Dm C
Now and then I think of when we were together
Dm C Dm C Dm C Dm C
Like when you said you felt so happy you could die
Dm C Dm C
Told myself that you were right for me
Dm C Dm C
But felt so lonely in your company
Dm C Dm C Dm C Dm C
But that was love and it's an ache I still remember
You can get addicted to a certain kind of sadness
Dm C Bb C
But you didn't have to cut me off
Dm C Bb
Make out like it never happened
C Dm
And that we were nothing
C Bb C
And I don't even need your love
Dm C
But you treat me like a stranger
Bb C
And that feels so rough
Dm C Bb C
You didn't have to stoop so low
Dm C Bb
Have your friends collect your records
C Dm
And then change your number
C Bb C
I guess that I don't need that though
Dm C Bb C
Now you're just somebody that I used to know
Dm C Dm C Dm C Dm C
Now and then I think of all the times you screwed me over
Dm C Bb C Dm C Dm C
But had me believing it was always something that I'd done
Dm C Bb C
And I don't wanna live that way
Dm C Bb C
Reading into every word you say
Dm C Bb C
You said that you could let it go
Dm C Bb C
And I wouldn't catch you hung up on somebody that you used to know...
(Refrão)
Dm C Bb C
I used to know
Dm C Bb C
That I used to know (2x)
Dm C Bb C
Somebody...
