(Adam Levine)
Now and then I think of when we were together
Like when you said you felt so happy you could die
I told myself that you were right for me
But felt so lonely in your company
But that was love and it´s an ache I still remember

(Christina Grimmie)
You can get addicted to a certain kind of sadness
Like resignation to the end, always the end

(Adam Levine & Christina Grimmie)
So when we found that we could not make sense
Well you said that we would still be friends
But I´ll admit that I was glad that it was over

She didn´t have to cut me off
Make out like out it never happened and that we were nothing
And I don´t even need your love
But you treat me like a stranger and that feels so rough

No you didn´t have to stoop so low
Have your friends collect your records and then change your number
I guess that I don´t need that though
Now you´re just somebody that I used to know
Now you´re just somebody that I used to know

(Christina Grimmie)
Now and then I think of all the times you screwed me over
But had me believing it was always something that I´d done
But I don´t wanna live that way
Reading into every word you say
You said that you could let it go
And I wouldn´t catch you hung up on somebody that I used to know

(Adam Levine & Christina Grimmie)
She didn´t have to cut me off
Make out like out it never happened and that we were nothing
And I don´t even need your love
But you treat me like a stranger and that feels so rough

No you didn´t have to stoop so low
Have your friends collect your records and then change your number
I guess that I don´t need that though
Now you´re just somebody that I used to know

Somebody (I used to know)
Now you´re just somebody that I used to know
Somebody, yeah, yeah, yeah

Now you´re just somebody that I used to know
