VERSE 2: REPEAT C G D

Take a sip of the high life
Chase it down until you fall
Three hundred sixty five nights
Why just one if we can have them all

Drop your calls, lose your keys
Before the drinks are gone
Get yourself out your seat
oh oh
Clap your hands, move your feet
Until the break of dawn
Cause nobody gives a damn about the day that you were born

CHORUS: REPEAT C G D G 

This song is for everyone who it ain't your birthday
You gotta party like it's not, party like it's not
This song's for anyone who is having the worst day
You gotta party like it's not, party like it's not
oh o oh

Party like it's not, Party like it's not,
Like it's not your birthday
Party like it's not, party like it's not
oh o oh
Party like it's not, party like it's not,
Like it's not your birthday
Party like it's not. party like it's not
oh o oh


BRIDGE: REPEAT C D G
                          G Bm C 

Ok lets loose control
I wanna see everybody on the floor
Go and send your invitations
Do it now 'cause time it wasten'
Life is tough, so listen up
DJ turn that weekend up
Get down, get loud, everybody stand up
Everybody go nuts, throw your hands up
Ok everybody now here's the plan
We're gonna dance until we cannot stand
Move your feet to every beat
Bump back, bring it back
Put it on repeat
When the crowd goes wild
You know it's on
If you wanna party then here's your song
It's alright, it's ok it's not even my birthday!

CHORUS: REPEAT C G D G 


Party like it's not, party like it's not
Party like it's not, party like it's not
Like it's not your birthday
Party like it's not, party like it's not
oh o oh
Party like it's not, party like it's not

This song is for everyone who it ain't your birthday
You gotta party like it's not, party like it's not
This song's for anyone who is having the worst day
You gotta party like it's not, party like it's not
oh o oh
(Like it's not your birthday)
Party like it's not, party like it's not
(Like it's not your birthday)
Party like it's not, party like it's not

(Like it's not your birthday)
Party like it's not, party like it's not

Party like it's not, party like it's not
