What You Waiting For? Lily Allen

[Intro]
Na-na-na-na-na na-na-na
Na-na-na-na-na na-na-na
Na-na-na

[Verse 1]
Since we separated
I've been suffocated, ah yeah
All the empty space in my head
First I felt liberated by it
But solitude is overrated
The other day I swear someone said
"Someone else is sharing your bed"
Maybe you picked up where I left
Now my heart is sinking
I don't know what I've been thinking

[Pre-Chorus]
I turned a strong man weak
I threw him down, brought him to his knees
I'm hoping somehow he'll forgive me
I think to myself

[Chorus]
What you waiting for?
You'll never be sure
Swinging back and forth
Just leave him alone
What you waiting for?
You'll never be sure
Swinging back and forth
I just don't know, know, know
