[Intro: Lupe Fiasco]
And what we have here
Snoddy great, Trey

[Chorus: Trey Songz]
Girl, I want you to know
I can't get you out of my head, my head, my head
Girl, I want you to know
I don't even know what you did, you did you did, but I love it

[Verse 1: Lupe Fiasco]
Uh uh, everythin' hooks
Everythin' works, you're a real good chorus
I'm a real good verse, freestyle unrehearsed
So clean, no curse
And when the song's gone, man everythin' hurts
So I put it in reverse, go back to the scene where I seen you first
Yeah, I need you to sing that single again
Play that video I seen you up in
A hundred million spins in my mind all day
Callin' requests on the line always
Yeah, the president of your fan club
Leave them players all behind like a band love

[Chorus: Trey Songz & Lupe Fiasco]
Girl, I want you to know
I can't get you out of my head, my head, my head
(I can't get you out now) Girl, I want you to know
I don't even know what you did, you did you did, but I love it
[Verse 2: Lupe Fiasco]
Playa need a minute
Like a time out in tennis 'fore I finish
How'd I get in this, maybe 'was your hair, maybe 'was your flair
Maybe it's the heels and the way you wear
Maybe it's you're real and the way you care
You don't care if I'm ill or a millionaire
The only thing that matters that the feeling's there
Your smile's so bright it's like a grill's in there
High off life, don't need a pill in there, nah
You're killin' me, I think I need a will in here
Got me feelin' real skills impaired
Hard to describe why you're still in here

[Chorus: Trey Songz]
Girl, I want you to know
I can't get you out of my head, my head, my head
Girl, I want you to know
I don't even know what you did, you did you did, but I love it

[Bridge: Trey Songz & Lupe Fiasco]
Don't care what nobody say 'cause I like it girl
Might go crazy tryna figure this out, love
But I like it girl
Don't even know why I feel this way 'cause I like it girl
Caught up in something that I can't get out of
But we like it girl
C'mon
[Chorus: Trey Songz & Lupe Fiasco]
Girl, I want you to know
I can't get you out of my head, my head, my head
I can't get you out now, said, I can't get you out now
(I want you to know) Girl, I want you to know
I don't even know what you did, you did you did, but I love it
Girl, I want you to know, I want you to know
I can't get you out of my head, my head, my head
Lupe, Trey, yeah (I want you to know)
Girl, I want you to know
I don't even know what you did, you did you did, but I love it
Just making sure, I don't even know

[Outro: Lupe Fiasco & Trey Songz]
Lupe, Trey
I can't get you out of my head, my head
