This is a song where you can play it a few different ways depending on how capable you are:

You could go through the whole song with just F#m, D, and A, but I'm going to tab it as 
think sounds best.

Also, you'll have to listen to the song to get an idea of rhythm for the chords,
as sometimes they stop or leave out a few,
and during the rap sections you can more or less make up your own rhythm
as long as you keep playing the chords for the right length of time

Note: This probably sounds best on an acoustic guitar though you could play it on electric.

Tuning: Standard EADGBe

prefer.

First Verse:
As I said earlier use your own rhythm here, whatever you think fits with the song, I'll 
give you the chords.
Also you can just play the lowest 3 strings and it sounds fine.

  F#m  Dsus2   A   E/G#
e|--2----5--|--5----4--|
B|--2----5--|--5----5--|
G|--2----7--|--6----4--|
D|--4----7--|--7----6--|
A|--4----5--|--7----7--|
E|--2-------|--5----4--|

Second Chorus:
Again, use what rhythm you think fits with the song

   F#m      D   A
e|--2----|--5---5--|
B|--2----|--7---5--|
G|--2----|--7---6--|
D|--4----|--7---7--|
A|--4----|--5---7--|
E|--2----|------5--|

Second Verse:
Same as the First Verse

  F#m  Dsus2   A   E/G#
e|--2----5--|--5----4--|
B|--2----5--|--5----5--|
G|--2----7--|--6----4--|
D|--4----7--|--7----6--|
A|--4----5--|--7----7--|
E|--2-------|--5----4--|

Third Chorus:
Same as the Second Chorus

   F#m      D   A
e|--2----|--5---5--|
B|--2----|--7---5--|
G|--2----|--7---6--|
D|--4----|--7---7--|
A|--4----|--5---7--|
E|--2----|------5--|

Outro:
You could repeat the chorus chords here but I think it sounds good if you just alternate 
F#m and D.

   F#m      D
e|--2----|--5----|
B|--2----|--7----|
G|--2----|--7----|
D|--4----|--7----|
A|--4----|--5----|
E|--2----|-------|

finish on F#m


That's it! Not too hard if you know the song and can play barre chords, please rate 
etc. Or don't, whatever...
