ダンスフロアに　愛情を込め
夢と感動を振りまく　Everyday
いつかはきっと　太陽のように
みんなを　照らすわ

触らないで気安く
邪魔しないで　私の時間

欲しいならば今すぐ
ふざけないで　口説けばいい

アイサレタイノニ…

どんな寂しい日だって
感じさせないから

ダンスフロアに　魂を込め
汗と青春を振りまく　Everyday
誰にだって知られたくない
秘密もあるが
私は何も　出し惜しまない
何にも　怖くない

終わった事とやかく
聞く気なんてないのだけど

確かめたいことなら
目を見つめて　聞いてごらん

アイサレタイノニ…

どんな悲しい日だって
信じる力で

ダンスフロアに　愛情を込め
夢と感動を振りまく　Everyday
どんな時も　忘れたくない
私のセオリー
いつかはきっと　太陽のように
みんなを　照らすわ

ダンスフロアに　魂を込め
汗と青春を振りまく　Everyday
誰にだって知られたくない
秘密もあるが
私は何も　出し惜しまない
何にも　怖くない

DANSU FUROA ni aijou wo kome
Yume to kandou wo furimaku Everyday
Itsuka wa kitto taiyou no you ni
Minna wo terasu wa

Sawaranaide kiyasuku
Jama shinaide watashi no jikan

Hoshii naraba ima sugu
Fuzakenai de kudokeba ii

Aisaretai no ni...

[Fu/Su] Donna samishii hi datte
[Ik/Say] Kanjisasenai kara

[Fu/Su] DANSU FUROA ni tamashii wo kome
Ase to seishun wo furimaku Everyday
Dare ni datte shiraretakunai
Himitsu mo aru ga
Watashi wa nan mo dashioshimanai
Nan ni mo kowakunai

Owatta koto toyakaku
Kiku ki nantenai no dakedo

Tashikametai koto nara
Me wo mitsumete kiite goran

Aisaretai no ni...

[Ik/Say] Donna kanashii hi datte

DANSU FUROA ni tamashii wo kome
Ase to seishun wo furimaku Everyday
Dare ni datte shiraretakunai
Himitsu mo aru ga
Watashi wa nan mo dashioshimanai
Nan ni mo kowakunai

Put your love on the dance floor
Dreams and emotions scatter Everyday
Someday surely Everyone will shine
Like the sun

Don't touch me so familiarly 
Don't disturb my time

If you want me Right now
Don't fool around, seduce me

Even though I want to be loved...

No matter what day
I won't let you feel lonely

Put your soul on the dance floor
Sweat and youth scatter Everyday
Everyone has a secret they don't
want anyone to know
I won't be stingy
I'm not afraid of anything

Somehow or other things are over
But I'm not in the mood to listen

If you want to make sure
Look into my eyes and listen

Even though I want to be loved...

No matter what kind of sad day
With the power of belief

Put your love on the dance floor
Dreams and emotions scatter Everyday
No matter when I don't want to forget
My theory
Someday surely Everyone will shine
Like the sun

Put your soul on the dance floor
Sweat and youth scatter Everyday
Everyone has a secret they don't
want anyone to know
I won't be stingy
I'm not afraid of anything
