堅苦しい話ばっかり　そういうのもう止めにしてさ
嬉しい時はめちゃくちゃ騒いで　悲しい時は思いきり泣いて
なんかそんなんで良くない？
 
ちょっと！ちょっと！そんなことよりも　とりあえず一緒に踊りましょ
順序もルールもどうだっていい　単純なのが大歓迎
ちょっと！ちょっと！まずは景気付けに　美味しいものでも食べましょ
そこの君　顔が引きつってる　だいたい　真面目過ぎるんじゃないの？
たまには　そう　お気楽主義で
 
いいんじゃない？楽しけりゃいいんじゃない？
いいんじゃない？楽しめばいいんじゃない？
 
いつだって楽しんだもん勝ち　熱くなれることに汗をかこう
悔しい時は何度でも叫んで　寂しい時は誰かを頼って
それがシンプルで良くない？
 
面倒くさいことをアレンジして　一回でも多く笑いましょ
詰め込み過ぎて頭でっかち　学べばいいってもんでもないでしょ
この際　そう　楽観主義で
 
ちょっと！ちょっと！そんなことよりも　なんだったら派手に踊りましょ
順序もルールもどうだっていい　単純なのが大歓迎
ちょっと！ちょっと！せっかくの人生　一回でも多く笑いましょ
そこの君　顔が引きつってる　だいたい　真面目過ぎるんじゃないの？
ちょいちょい　そう　お気楽主義で
 
いいんじゃない？
楽しけりゃいいんじゃない？
いいんじゃない？
楽しめばいいんじゃない？
いいんじゃない？
楽しんだ人がWINじゃない？
いいんじゃない？
そういうことでWINじゃない？

You keep speaking so formally, please stop that already
When you're happy you should really smile, and when you're sad cry as much as you like
Isn't that really great?
 
Hey! Hey! Rather than that stuff, why don't we dance together
Forget about the rules and procedures, even if they're easy I prefer a warm welcome
Hey! Hey! First you should put some life into it, and let's eat something delicious
Hey you, your face is all hard and stiff, aren't you being too serious here?
Every now and then you need to be carefree, that's my principle
 
Isn't it all right? Isn't it all right to enjoy yourself?
Isn't it all right? Isn't it all right to enjoy yourself?
 
At any time the fun thing is what wins, when it's hot you sweat it out
When it's frustrating you should yell out anything, when you're lonely rely on others
It's simple, isn't that great?
 
You should arrange the troublesome things, so that you can still smile and be carefree at least once
If you cram too much then you'll become top-heavy, you'll learn it in the lesson anyway so no problem
In this occasion you need to be optimistic
 
Hey! Hey! Rather than that stuff, why don't we show off and dance
Forget about the rules and procedures, even if they're easy I prefer a warm welcome
Hey! Hey! Since this is your life, you should smile and be carefree at least once
Hey you, your face is all hard and stiff, aren't you being too serious here?
Every now and then you need to be carefree, that's my principle
 
Isn't it all right?
Isn't it all right to enjoy yourself?
Isn't it all right?
Isn't it all right to enjoy yourself?
Isn't it all right?
Don't people who have fun win?
Isn't it all right?
Isn't that sort of thing a win?
