[Intro]
Em7 Cadd9 G Dsus4/F#

[Verse 1]
Em7                                                                Cadd9
The first shots fired, everybody’s gathered around
G
You’re looking at me like I tried to take you down
Dsus4/F#
No, no, it’s not what happened at all
Em7                                                       Cadd9
There’s no sound, I’m waiting on your next move
G
A showdown and I know where to hit you
Dsus4/F#
But no, no, it’s not how I wanted this to go down

[Pre-Chorus]
Cadd9
Now we’re standing in the ring
Dsus4/F#
And you made your first swing

And now we’re fighting dirty
Cadd9                   Em7                   Dsus4/F#
Won’t somebody come say “break it up!”

[Chorus]
Cadd9                                     G
And I used to be on your side
Dsus4/F#                   Em7
Now it’s looking like we’re going to battle
Cadd9                                                       G
And why you’re taking shots at me like
Dsus4/F#                                     Em7
Somebody’s gonna give you a medal?
Cadd9                                     G
And I never wanna hurt you
Dsus4/F#                                     Em7
But I’m tired of taking all these blows
Cadd9                           G
And so I’d rather be on your side
Dsus4/F#                   Em7
But if you wanna fight
Cadd9 G Dsus4/F# Em7
Baby let’s go, oh, oh
Cadd9 G Dsus4/F#
Let’s go, oh, oh

[Verse 2]
Em7                                     Cadd9
So gloves off, if this is how you want it
We had it all, but you couldn’t keep a promise
G                                                       Dsus4/F#
No, no, I’m not the one who tore us apart
Em7
Let me remind you for a minute why we’re not fine
Cadd9
Is she here? Is she’s standing on the sidelines?
G                                                       Dsus4/F#
Oh, oh, can’t you tell this is breaking my heart?

[Pre-Chorus]
Cadd9
Now we’re standing in the ring
Dsus4/F#
And you made your first swing
And now I’m fighting dirty
Cadd9                   Em7                   Dsus4/F#
But I ain’t going down till they break it up

[Chorus]
Cadd9                                     G
And I used to be on your side
Dsus4/F#                                                 Em7
Now it’s looking like we’re going to battle
Cadd9                                 G
And why you’re taking shots at me like
Dsus4/F#                                 Em7
Somebody’s gonna give you a medal?
Cadd9                                 G
And I never wanna hurt you
Dsus4/F                                                 Em7
But I’m tired of taking all these blows
Cadd9                                 G
And so I’d rather be on your side
Dsus4/F#                 Em7
But if you wanna fight
Cadd9 G Dsus4/F# Em7
Baby let’s go, oh, oh
Cadd9 G Dsus4/F# Em7
Let’s go, oh, oh

[Bridge]
Cadd9
Now we’re standing in the ring
Dsus4/F#
Breaking everything that we’ve been building up so long
Cadd9 Em7 Dsus4/F#
And I don’t wanna do this breaking up
Em7* Dsus4/F#* Cadd9*
But you’re not who I thought you were
Em7* Dsus4/F#* Cadd9
And this is looking more like a war
Cadd9 G Dsus4/F# Em7
Like a war
Cadd9 G Dsus4/F# Em7
Looks like we’re going to war

[Chorus]
Cadd9* G*
And I used to be on your side
Dsus4/F#* Em7*
Now it’s looking like we’re going to battle
Cadd9* G*
And I’m trying not to break down crying
Dsus4/F# Em7
No one’s gonna give you a medal
Cadd9 G
And I never wanna hurt you
Dsus4/F Em7
But I’m tired of taking all these blows
Cadd9 G Dsus4/F# Em7
And so I’d rather be on your side
Cadd9 G
I’d rather be on your side
Dsus4/F# Em7
But if you wanna fight
Cadd9 G Dsus4/F# Em7
Baby let’s go, oh, oh
Cadd9 G Dsus4/F# Em7
Looks like we’re going to war , oh, oh

[Outro]
Em7 Cadd9
The first shots fired, everybody’s gathered around
G
You’re looking at me like I tried to take you down
Dsus4/F#
No, no, but if you wanna fight, baby, let’s go
