Capo 6

C Em Am G

C                         Em
I hopped off the plane at L.A.X.
Am                           G
With a dream and my cardigan
C                           Em
Welcome to the land of fame excess,
Am             G
Am I gonna fit in?

C     
Jumped in the cab,
         Em                 Am
Here I am for the first time
                                         G
Look to my right and I see the Hollywood sign
C                   Em
This is all so crazy
Am                       G
Everybody seems so famous

C                          Em                     Am
My tummy's turnin' and I'm feelin' kinda home sick
                                  G
Too much pressure and I'm nervous,
C                                  Em
That's when the taxi man turned on the radio
Am                     G
And a Jay-Z song was on
And the Jay-Z song was on
And the Jay-Z song was on

[Chorus]
            C
So I put my hands up
        Em              Am
They're playing my song,
                            G
And the butterflies fly away
    C                    Em  Am
I'm noddin' my head like yeah 
                            G   
I'm movin' my hips like yeah
         C
I got my hands up,
        Em             Am
They're playin' my song
                      G
I know I'm gonna be OK
C Em Am                      G
Yeah, it's a party in the USA
C Em Am                      G
Yeah, it's a party in the USA

C                     Em
Get to the club in my taxi cab
Am                           G
Everybody's looking at me now
     C                         Em
Like "Who's that chick, that's rockin' kicks?
Am                            G
She gotta be from out of town"

C               Em                 Am
So hard with my girls not around me
                                     G
It's definitely not a Nashville party
C                    Em       Am
'cause all I see are stilettos
                            G
I guess I never got the memo

C                          Em                     Am
My tummy's turnin' and I'm feelin' kinda home sick
                                 G
Too much pressure and I'm nervous
C                               Em
That's when the D.J. dropped my favorite tune
Am                     G
and a Britney song was on
and a Britney song was on
and a Britney song was on

[Chorus]

            C
So I put my hands up
        Em              Am
They're playing my song,
                            G
And the butterflies fly away
    C                    Em  Am
I'm noddin' my head like yeah 
                            G   
I'm movin' my hips like yeah
         C
I got my hands up,
        Em             Am
They're playin' my song
                      G
I know I'm gonna be OK
C Em Am                      G
Yeah, it's a party in the USA
C Em Am                      G
Yeah, it's a party in the USA

Em                     Am
Feel like hoppin' on a flight (on a flight)
Em                     Am
Back to my hometown tonight (town tonight)
Em                       Am
Something stops me every time (every time)
F                                 G
The DJ plays my song and I feel alright

[Chorus x2]

            C
So I put my hands up
        Em              Am
They're playing my song,
                            G
And the butterflies fly away
    C                    Em  Am
I'm noddin' my head like yeah 
                            G   
I'm movin' my hips like yeah
         C
I got my hands up,
        Em             Am
They're playin' my song
                      G
I know I'm gonna be OK
C Em Am                      G
Yeah, it's a party in the USA
C Em Am                      G
Yeah, it's a party in the USA
