I couldn?t find any guitar chords on this song on here, so I decided to do one on my 
I am pretty sure these chords are right. So if not then you can probably tweak it to fix it.

HALF STEP DOWN

INTRO

D Cadd9 G

VERSE

D
Roll into town
Cadd9
Step off the bus
G
Shake off the where you came from dust
D
Grab your guitar
Cadd9
Walk down the street
G
Sign says Nashville, Tennessee

PRE-CHORUS
Cadd9
But I,
         G
have found

CHORUS

           D                          Cadd9
It?s a crazy town full of neon dreams
G
Everybody plays, everybody sings
D                            Cadd9
Hollywood with a touch of twang
G
To be a star, you gotta bang bang bang
D                                       Cadd9
Bend those strings till the hank comes out
G
Make all the drunk girls scream and shout
      Cadd9
We love it, we hate it

          G                         D
Were all just trying to make it

In this crazy town

This just repeats for the next verse and chorus

BRIDGE

Cadd9                                   G
One year they reposes your truck
              Cadd9                              D
And the next you make a couple million bucks
