Patrice - No Excuse chords

There's already a tab of this song on ultimate-guitar but to me it looked a bit 
wrong and confusing although it was pretty close. So just to make it clearer:
 
         Gm
Them ah chat like them bad
         F
But them don't know what them do
             Gm
All of them flex like idiot
              F
Them must be mad, them must be fool
            Gm
There's so much them forgot
                   F
When them type of people there pass through
           Gm
I just say. Stupidness is no excuse. Jah!

Cm                                Bb
Enough men ah gawn like them are bad man, bad man
Cm                  Bb
But badness nah go pay
Cm                      Bb
It can pay your rent today and tomorrow but
Cm                          Bb
What about the end of the day?
Cm                             Bb
Others ah gawn like them are big man, big man
Cm                             Bb
And suck out the blood of the poor
Cm
But allmighty JahJah
  Dm
I see everything
               Eb
So there's no need to be fake
               F
Cause your judgement you can't escape
