You Will Never Know的詞曲作者和演唱者不詳，但是可以提供一些歌詞供您參考。
歌詞如下：
You will never know
What you're leaving behind
But time will show
You were always on my mind
When you thought that I was through
Just being blue
And crying alone in the night
You will never know
How I feel about you
And I thought I had lost all
The way you treated me
You broke my heart
And you hurt me so
But baby now I'm through
And I'm gonna show you so
You will never know
What you're leaving behind
But time will show
You were always on my mind
Now I'm feeling fine
I'm feeling high on life
And I'm gonna take you back in time
And leave you stranded baby
You will never know what you're losing now
