Lyric:

It’s my day and your day
It’s a party, party
불꽃아 타올라 어서 빨리빨리
오늘 밤 (Yeah) we rock the world (Just rock the world)
I can make the beat go
Bam-bam, ba-ra, bam-ba-ram, ba-ra
바로 오늘이야
It’s your birthday, birthday (Birthday)
Bam-bam, ba-ra, bam-ba-ram, ba-ra
온 세상이 shine and so icy, icy
Birthday, birthday 딱 지금이야
Party pop, pop the champagne (Wow, pop, pop the champagne)
우리 맘대로 이뤄지지
더 꿈꾸고 바래 bi-bi-bi-birthday
