Just a fraction of your love
It fills the air
And I fall in love with you
All over again
Ooh
You're the light that faced the sun
In my world
I'd face a thousand years of pain
For my girl
Out of all the things in life
That I could fear
The only thing that would hurt me
Is if you weren't here
Woah
I don't want to go back
To just being one half of the equation
You understand what I'm sayin'

Girl with out you I'm lost
Can't face this focus at heart
Between me and love
You're the common denominator
oh, oh, ohh, oh
You're the common denominator
oh, oh, ohh, oh

Before your love was low
Now you're just my height
We chase the game that would put
My cot in the side, aye

Broken heart rise up to say
Love is alive
You and I would stand
To be multiplied, yeah
Out of all the things in life
That I could fear
The only thing that would hurt me
Is if you weren't here --
Yeah
I don't want to go back
To just being one half of the equation
You understand what I'm sayin'
Girl with out you I'm lost
Can't face this focus at heart
Between me and love
You're the common denominator
oh, oh, ohh, oh
You're the common denominator
oh, oh, ohh, oh

I'm never ever not
Without your touch
Every kiss that you give
It gives me heart
And to all the heart it can
Jealous females hate it
I'ma hold it down for you
For you, woah, oh woah
Common denominator
Oh, yeah, woahh
I don't wanna to go back
I don't want to go back
To just being one half of the equation
You understand what I'm sayin'
Girl with out you I'm lost
Can't face this focus at heart
Between me and love
You're the common denominator
oh, oh, ohh, oh
You're the common denominator
oh, oh, ohh, oh

Just a fraction of your love
fills the air
And I'd fall in love with you
all over again
