Hey there, this is my first tab, but I think it sounds pretty good that way.

I structured this song in three parts:

1. Intro and verse: G   F  (listen to the song to figure out the rhythm)

Intro: play four times G  F

         G
Them ah chat like them bad
         F
But them don't know what them do
             G
All of them flex like idiot
              F
Them must be mad, them must be fool
            G
There's so much them forgot
                   F
When them type of people there pass through
I just say...stupidness is no excuse

2. Chorus (same rhythm as verse):   C(sounds better when played as barre) Bb

C                                Bb
Enough men ah gawn like them are bad man, bad man
C                  Bb
But badness nah go pay
C                      Bb
It can pay your rent today and tomorrow but
C                          Bb
What about the end of the day?
C                             Bb
Others ah gawn like them are big man, big man
C                             Bb
And suck out the blood of the poor

3. End of chorus (still the same rhythm)

Sry I don't quite know how these chords are called, I just figured them out by listening 
the song so I will tab them this way.
First one is again C
I will call the following ones 2, 3, 4, because I don't know them...I hope you don't mind...

So then it goes:
     2:      3:      4:
 e----5--5----6--6----8--8----|
 B----5--5----6--6----8--8----|
 G----7--7----8--8----10-10---|
 D----7--7----8--8----10-10---|
 A----5--5----6--6----8--8----|
 E----5--5----6--6----8--8----|

That's they way it's supposed to be played:

C
But allmighty JahJah
   2
I see everything
               3
So there's no need to be fake
            4
Cause your judgement you can't escape

Chorus again...and so on...

I hope you enjoy this great song!
