《What You Know》的歌詞如下：
Verse 1：
You say you're going out for a while
You're gonna take your time and take your toll
I'm going to my room and I'll be alright
I'll wait for you there with the radio on
Chorus：
What you know about my dreams?
About the way I feel and all the things I've seen
What you know about my fears?
About the times I cried and all the things I've been through
Verse 2：
You said it's not about the distance between us
It's about the time you said goodbye and left me behind
I don't want to feel alone tonight
I'll wait for you there with the radio on
Bridge：
You say you're going out for a while
But when you come back I won't be here anymore
Chorus：...（重複）
Outro：
What you know about the pain?
About the dreams that might never come true again
What you know about the gain?
About the hope that lies within all those years ahead.
