《World Apart》的歌詞如下：
女：
I can't sleep,
Can't turn off my mind,
When will this end?
You're on my mind all the time,
Can't get you off my mind,
男：
I'm trying hard to move on,
But I keep coming back to you,
You're the only one on my mind,
女：
Every night, every day,
I'm feeling this way,
Can't get you out of my head,
男：
Every night, every day,
I'm stuck in my head,
Can't get you out of my head,
女：
We're worlds apart,
But I feel your heartbeat,
In my chest,
It's like you're right here beside me,
男：
We're worlds apart,
But I feel your breath on my neck,
Every night, every day,
女：
I can't stop this feeling,
男：
Can't stop this feeling,
女：
It won't go away,
男：
It won't go away,
女：
It won't go away, no no no no,
男：
No no no no.
