Common Denominator [Bonus Track]
 作词 : Justin Bieber/Lashaunda Carr
 作曲 : Justin Bieber/Lashaunda Carr
Just a fraction of your love fills the air,
And I fall in love with you all over again,

You're the light that feeds 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
Do you understand what I'm sayin'?
Girl without you I'm lost
Can't fix this compass 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, playin' girls was my high
You changed the game now I put my card in the side, aye
When broken hearts rise up to say love is a lie
You and I will stand to be love's reply, yeah
Out of all the things in life that I could fear, yeah
The only thing that would hurt me is if you weren't here, here, here
Yeah, Yeah
I don't want to go back
To just being one half of the equation
Do you understand what I'm sayin'? （do you understand?）
Girl without you I'm lost
Can't fix this compass 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 can't imagine life without your touch,
And every kiss that you give, you fill me up
And through all the heart achin' and jealous females hatin'
Imma hold it down for you, you
Oh, whoa...
Your the common denominator,
Oh, yeah, woahh,
I don't wanna to go back,
I don't wanna go back
To just be one half of the equation （half of the equation）
Do you understand what I'm sayin'? （oh, whoa）
Girl without you I'm lost
Can't fix this compass 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 fall in love with you all over again...
