Necesito una cosa

But i need one thing 

Get out, get out, get out of my head
And fall into my arms instead
I don't, I don't, don't know what it is
But I need that One Thing
Yeah, you've got that One Thing
Now I'm climbing the walls
But you don't notice at all
That I'm going out of my mind
All day and all night
Some things gotta get loud
Cuz I'm dying just to know your name
And I need you here with me now
Cuz you've got that One Thing
