I've been running up all night
  I've been running up all night
But it's 2am and I can't think about anything but you
I've been running up all night
I've been running up all night
With a tight chest and a conscience
I can't get out of my head
All I think about is you, you
All the calls that I know you saw
But you said didn't come through
So all I think about is you, you
All the things I could say to make you think
I'm with you-know-who
These insecurities
Are gonna ruin me
And I know this jealousy will ruin us
We gotta stop faster than we can run
We are twenty-first century love
It's 4am and I don't wanna know
All the things that you are gonna do
Without me by your side
Without me by your side
I've been running up all night
I've been running up all night
With million reasons why
And another million reasons why
All I think about is you, you
And that face that you make when you want her
But you say you don't
These insecurities
Are gonna ruin me
And I know this jealousy will ruin us
We gotta stop faster than we can run
We are twenty-first century love
Yeah we are twenty-first century love
All I think about is you, you, you
All I think about is
These insecurities
Are gonna ruin me
And I know this jealousy will ruin us
We gotta stop faster than we can run
We are twenty-first century love
Yeah we are twenty-first century love
We are twenty-first century love
Yeah we are twenty-first century love
