Aah-aah
Aah-aah

You can knock on the door, but I'm not gonna let you in
You can play all your games, but I'm not gonna let you win again
You can step to me with all your negativity, uh
Don't you know I'm just so over you under my skin

And this time it's not even anger
I think we're just better as strangers
Don't try the locks 'cause I changed them

You can't have my head space
(Aah-aah)
Won't let you in my safe place
(Na-na, oh, na-na-na, yeah)
You can say what you want, you can do what you like
You can throw another stone, but you're never gonna see my heart break
No, no

'Cause you can't have my headspace
You, you, you can't have it (aah-aah)

For the first time, I ain't gonna give you a second thought (nah-nah)
'Cause your talk is so cheap that the pain isn't worth the cost
So do your worst to me but you'll never get the best of me
'Cause I know who I am, don't tell me what I'm not

Now I like the way I feel brand new
Matter of fact, I should thank you
I'm stronger for what you put me through

You can't have my headspace
(You can't have my headspace)
Won't let you in my safe place
(Na-na, oh, na-na-na, hey)
You can say what you want, you can do what you like
You can throw another stone, but you're never gonna see my heart break
No, no (you can't)

'Cause you can't have my headspace (you, you)
You can't have it
No, you can't have my headspace (you, you)
You can't have it

One, two, three, four
Don't you come round here no more
Five, six, seven, eight
You can try but it's too late
Eight, seven, six, five
Finally, got you off my mind
Four, three, two, one
I'm done

You can't have my headspace (headspace)
Won't let you in my safe place
(Na-na, oh, na-na-na, hey)
You can say what you want, you can do what you like
You can throw another stone, but you're never gonna see my heart break
No, no (you can't)

'Cause you can't have my headspace (you, you)
You can't have it
No, you can't have my headspace (you, you)
You can't have it

'Cause you can't have my headspace (you, you)
You can't have it
No, you can't have my headspace (you, you)
You can't have it

You can't have my headspace
