Every clock is ticking faster
Taking trips around the sun
Another year, another chapter
5 and 4 and 3 and 2 and 1Drop your calls, lose your keys
Before the drinks are gone
Get yourself out your seat
Oh, ohQuit your bitchin', move your feet
Until the break of dawn
'Cause nobody gives a damn about
The day that you were bornExcept for everyone who ruins 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 notOh-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 notOh-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-ohTake a sip of the good life
Chase it down until you fall
300 and 65 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, ohClap your hands, move your feet
Until the break of dawn
'Cause nobody gives a damn about
The day that you were bornThis song's for everyone who ruins 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 notOh-o-oh
