[第一節]
I can't stop
Can't stop thinking
Can't stop thinking about you
I can't stop
Can't stop thinking
Can't stop thinking about you tonight
[副歌]
Halloween
I'm all out of my senses
Halloween
With every second I'm getting closer
[第二節]
I can't breathe
Can't breathe thinking
Can't breathe thinking about it
I can't breathe
Can't breathe anymore
I want it more and more with you
[副歌]
Halloween
Just the two of us under the moon
Halloween
Running out of time, it's too late
But now it's for sure
You and me together, forever
[第三節]
My lips are sealed
And you're the key that unlocks me
But if you won't do it
Then I have to find my own way
[副歌]
Halloween
Just the two of us under the moon
Halloween
Running out of time, it's too late
But now it's for sure
You and me together, forever forever forever forever forever
[尾聲]
So let me know, let me know tonight yeah yeah yeah...Forever yeah yeah yeah...Forever yeah yeah yeah...Forever yeah yeah yeah...Forever yeah yeah yeah...Forever together.
