My first tab, to Jay Sean - Down (acoustic) hadn't seen these tabs transcribed 
before so decided to do it myself. 

A big thanks to Kay Zee for helping tab this.

Listen to the song and use your own intuition to find the strumming pattern.

Baby are you down down down down down,
Ab Bbsus4  Bb

              Ab                    Bbsus4       Bb

Carry on pattern for verse 2 and proceeding choruses.

(Verse 2)

Just let it be, come on and bring your body next to me,
I'll take you away, hey, turn this place into our private getaway,

(Pre-Chorus)
So leave it behind 'cause we, have a night to get away,
So come on and fly with me, as we make our great escape,

(So why don't we run away)

(Chorus)
So baby don't worry, you are my only, ooohh
You won't be lonely, even if the sky is falling down,
You'll be my only, no need to worry,
Baby are you down down down down down,
Down, Down,
Baby are you down down down down down,
Down, Down,
Even if the sky is falling down,

(Lil Wayne)

Down like she supposed to be,
She gets down low for me,
Down like her temperature, assuming she zero degree,
She cold, overfreeze,
I got that girl from overseas,
Now shes my miss America,
Now can i be her soldier please,
I'm fighting for this girl,
On the battlefield of love,
Don't it look like baby cupid sending arrows from above,
Don't you ever leave the side of me,
Indefinitely, not probably, 
And honestly Im down like the economy,
Yeahhhhhh

(Chorus)

So baby don't worry, you are my only,
You won't be lonely, even if the sky is falling down,
You'll be my only, no need to worry,
Baby are you down down down down down,
Down, Down,
Baby are you down down down down down,
Down, Down,
Even if the sky is falling down
