Lyrics:

The biggest lie you ever told
Your deepest fear about growing old
The loneliest night you ever spent
The angriest letter you never sent
The girl you swore you'd never leave
The one you kissed on New Year's Eve

The sweetest dream you had last night
Your darkest hour, your hardest fight
I wanna know you, like I know myself
I'm waiting for you, there ain't no one else
I wanna know you, inside out

Chorus:
I wanna dig down deep, I wanna lose some sleep
I wanna scream and shout, I wanna know you inside out
I wanna take my time, I wanna know you're mine
You know there ain't no doubt, I wanna know you inside out

The saddest song you ever heard
The most you said with just one word
The longest prayer you ever prayed
The truest vow you ever made
What makes you laugh, what makes you cry
What makes you mad, what gets you by
Your highest high, your lowest low
There are the things I wanna know

Chorus:
I wanna dig down deep, I wanna lose some sleep
I wanna scream and shout, I wanna know you inside out
I wanna take my time, I wanna know you're mind
You know there ain't no doubt, I wanna know you inside out

I wanna know your soul, I wanna lose control
Come on and let it out
I wanna know you inside out

Chorus:
I wanna dig down deep, I wanna lose some sleep
I wanna scream and shout, I wanna know you inside out
I wanna take my time, I wanna know you're mine
You know there ain't no doubt, I wanna know you inside out
