[Fabolous:]
Don't you hate a coulda, woulda, shoulda? (oh oh no, oh oh no)
Coulda did, woulda did, what you shoulda (oh oh no, oh oh no)
If I had a dollar for every should be you know how rich I would be
Like they say it is what it is, now what it could be, 
Can't cry feel guilt over spilled milk, 
I'm too fly, I'm too cool, word to versace silk, 
And my watch be filled with mad diamonds
I got good watches just bad timing
The chick I met at the club was cute, 
Still feel like I'm gettin' brain from the substitute, 
'Cause this ain't you and I ain't me, 
Complain you happy then why you're so mad at me, 
Can't hold on of what you had just what you got, 
You should be here, but you're not.
[Chorus - ne-yo:]
I'm doing it again, what I told myself I would not do, oh
It's 4:15 am I'm sitting here drinkin, reminisin' on you, oh
And how I used to let you smoke even though I don't
You'd get blowed then we both get low
As I lay here with some girl I don't know
In the back of my mind, one million times
I tell myself it should be you, should be you, should be you
And me right now said it should be you, should be you, 
Should be you and me right now uhh.
As I watch her sleep, all that I can think
She's beautiful but she's not you
Love her just a night, then out of my life
Damn why can I do just right, when you told me you wanted to leave
I pretended it didn't hurt me, 
But if I here I can hardly breathe, 
Laying next to she when in reality, it should be
[Chorus - ne-yo:]
It should be you, oh, should be you, should be you
And me, right now, right now
Said it should be you, should be you, 
Should be you and me, right now ah
Uhh uhh should be you, should be you baby ahh
[Diddy:]
Check this out, 
My life lights cameras fame and action, 
Feeling dreams from all these private planes I'm catchin'
Willing to trade all the flashy chains and flashin for a night
Back for us exchangin pain and passion, 
Romances, tryin to like the phantom doors you used to ride
Cause it's tryin to open up it's like suicide, 
God teaches lessons every day, 
You is all I needed like meth and mary j
The sun don't shine forever
Any time that we fall that just means we just climb together, 
Guess we avoided what we couldn't went through
That don't change the fact that it should have been you.
Girl it's should be you
[Chorus - ne-yo:]
It should be you, oh, should be you, should be you
And me, right now, right now
Said it should be you, should be you, 
Should be you and me, right now aha
Uhh uhh, I said it should be you, it should be you baby ahh
