slip out的中文意思是“溜走，不知不覺地出現，偷跑，外泄”。其歌詞如下：
Lying awake all night 我整夜無法入睡
You're out of reach 我抓不到你
Somewhere across the room 某個角落
The thoughts keep comin' like a secret song 思緒不停湧入 如同一首秘密的歌
Keep me up and keep me up all night 一直催促我，讓我整夜無法入眠
All through the darkest days 在最黑暗的日子裡
When you slip out 你悄然離去
Keep me up and keep me up all night 一直催促我，讓我整夜無法入眠
You're slipping out of my life 你從我的生活中悄然離去
Out of reach, out of sight 遙不可及，消失在視線之外
So I'll keep on singing these songs 所以我會繼續唱這些歌
Trying to catch you 你試圖抓住我
And I'll keep on dreaming tonight 今夜我會繼續做夢
Cause you slip out 因為你悄然離去
Verse 2:
You're standing in the doorway 你站在門口
Your face is turning cold 你的臉開始變冷酷
I'm feeling lost and empty 我感到迷失和空虛
And I don't know what to do 我不知道要做什麼
Chorus:
Keep me up and keep me up all night 一直催促我，讓我整夜無法入眠
All through the darkest days 在最黑暗的日子裡
When you slip out 你悄然離去
Out of reach, out of sight 遙不可及，消失在視線之外
So I'll keep on singing these songs 所以我會繼續唱這些歌
Try to find you 我試圖找到你
And I'll keep on dreaming tonight 今夜我會繼續做夢，等待你的歸來。
