xThe chords already on this site are pretty good, but I'm lazy so I transposed
them.  Here they are for your convenience :)
CAPO 5
[Intro]
Am  Dm  F7  E7
[Verse 1]
Am
 He left no time,
      Dm
To re-gret.
              F7
Kept his dick wet,
With his same old,
     E7
Safe bet.
Am
 Me,
            Dm
And my head high,
             F7
And my tears dry,
               E7
Get on without my guy.
[Verse 2]
Am
 You went back,
            Dm
To what you knew,
       F7
So far removed from,
                 E7
All that we went through.
    Am
And I tread,
           Dm
A troubled track,
            F7
My odds are stacked,
             E7
I'll go back to black.
[Chorus 1]
Am
 We only said good-bye,
     Dm
With words,
I died a hundred times.
F7
 You go back to her
    E7
And I go back to...
(n.C)        (Am) 
 I go back to us.
[Verse 3]
Am          Dm
 I love you much,
           F7
It's not e-nough.
You love blow,
      E7
And I love puff.
    Am
And life is like,
Dm
 A pipe,
               F7
And I'm a tiny penny,
Rolling up,
          E7
The walls inside.
[Chorus 2]
Am
 We only said good-bye,
     Dm
With words,
I died a hundred times.
F7
 You go back to her
    E7
And I go back to...
Am
 We only said good-bye,
     Dm
With words,
I died a hundred times.
F7
 You go back to her
    E7
And I go back to...
[Break]
(n.C)
[Bridge 1]

 Black,
Dm
 Black,
C
 Black,
E7
 Black.
Am
 Black,
Dm
 Black,
C
 Black,
E7
 I go back to...
I go back to...
[Chorus 3]
Am
 We only said good-bye,
     Dm
With words,
I died a hundred times.
F7
 You go back to her
    E7
And I go back to...
Am
 We only said good-bye,
     Dm
With words,
I died a hundred times.
F7
 You go back to her
    E7
And I go back to...
Am
 Black.
