They say I'm trouble
They say I'm bad
They say I'm evil
And that makes me glad
A dirty no-good
Down to the bone
Your worst nightmare
Can't take me home
So I've got some mischief
In my blood
Can you blame me?
I never got no love
They say I'm callous
A low-life hood
I feel so useless
MISUNDERSTOOD
Mirror, mirror
On the wall
Who's the baddest of them all?
Welcome to my wicked world, wicked world
I'm rotten to the core (core)
Rotten to the core
I'm rotten to the core (core)
Who could ask for more?
I'm nothing like the kid next, 
Like the kid next door
I'm rotten to the core
I'm rotten to the... core
Call me a schemer
Call me a freak
How can you say that?
I'm just... unique
What, me? A traitor?
Ain't got your back?
Are we not friends?
What's up with that?
So I'm a misfit
So I'm a flirt
I broke your heart?
I made you hurt?
The past is past
Forgive, forget
The truth is:
YOU AIN'T SEEN NOTHING YET! 
Mirror, mirror
On the wall
Who's the baddest of them all?
Welcome to my wicked world, wicked world
I'm rotten to the core (core)
Rotten to the core
I'm rotten to the core (core)
Who could ask for more
I'm nothing like the kid next
Like the kid next door
I'm rotten to the core
I'm rotten to the... core
~Instrumental~
I'm rotten to the core (core)
Rotten to the core
I'm rotten to the core (core)
Who could ask for more?
I'm nothing like the kid next
Like the kid next door
I'm rotten to the core
I'm rotten to the... core
