답답한 일상에 찌든 너
지루한 시간을 사는 너
똑같은 하루가 지겨워
던져버려 모두 다

No no 잊어 네 모습을
Jump jump 뛰어 세상위로
즐겨봐 오늘 밤
아침이 밝을 때까지

오늘 Friday Friday 짜릿해
우리 모두 하나 될 party time
오늘 Friday Friday 즐겨봐
Ohohoh 끝이 없는 이 밤

I want you happy happy tonight
I want you happy happy tonight

Ohohoh forever Friday night

축 처진 어깨로 걷는 너
커피로 하루를 버티는 너
웃음을 잃은 채 산다면
던져버려 모두 다

No no 잊어 네 모습을
Jump jump 뛰어 세상위로
즐겨봐 오늘 밤
아침이 밝을 때까지

그 모습이 더 어울린다

[English translation:]

You're tired from the frustrating daily routine
You're living in a boring time
If you're tired of the same days
Then throw it all away

No no, forget your image
Jump jump, jump to the top of the world
Enjoy the night
Until the morning comes

Today is Friday, Friday, it's electrifying –
We're gonna become one in this party time
Today is Friday, Friday, enjoy it
Oh oh oh, this endless night

I want you happy happy tonight
I want you happy happy tonight
I want you happy happy tonight
Ohohoh forever Friday night

You're walking with droopy shoulders
You survive each day with coffee
If you've lost your smile
Then throw it all away

No no, forget your image
Jump jump, jump to the top of the world
Enjoy the night
Until the morning comes

Today is Friday, Friday, it's electrifying
We're gonna become one in this party time
Today is Friday, Friday, enjoy it
Oh oh oh, this endless night

I want you happy happy tonight
I want you happy happy tonight
I want you happy happy tonight
Ohohoh forever Friday night

Uh tonight is Fri Friday
Everyone gather together
Find your hidden self tonight
Look at it
The earth is turning and the time is ticking
Feel the rhythm and enjoy the night
Yeah, you want party night
You look better like that

And become one in this party night
Today is Friday, Friday, let's play
Oh oh oh, on this good night
