Here is Katy Perry's Dark Horse:

Oh, no.

[Juicy J:]
Yeah
Ya'll know what it is

Katy Creeper
Slimey Slime, aha.
Let's rage

[Katy Perry:]
I knew you were
You were gonna come to me
And here you are
But you better choose carefully
'Cause I, I'm capable of anything
Of anything and everything

I've got pressure plates all over,
I've got stacks of TNT
So don't make me your enemy, your enemy, your enemy

So you wanna play with diamonds
Boy, you should know what you're falling for
Baby do you dare to do this?
Cause I'm coming at you with a diamond sword
Are you ready for, ready for
A perfect sword, perfect sword
Cause once you're in my mine, in my mine
There's no going back

Mark my words
This stuff will make you levitate
Like a ghast
Like a ghast without a cage
But down to earth
If you choose to walk away, don't walk away

It's all in your pick-axe now baby
It's a yes or no, no maybe
So just be sure before you give it all to me
All to me, give it all to me

So you wanna play with diamonds
Boy, you should know what you're falling for
Baby do you dare to do this?
Cause I'm coming at you with a diamond sword
Are you ready for, ready for
A perfect sword, perfect sword
Cause once you're in my mine, in my mine (love trippin')
There's no going back

[Juicy J - Rap Verse:]
Uh
She's a beast
I call her Kreeper (come back)
She blows you up
Like y'old dynamite (woo)
Be careful
Try not to tread on her
Pressure plates
Cause she got so much
You might fall into her trap
When you meet her
If you get the chance you better keep her
On your good side, give her diamonds
or she'll turn cold as a freezer
That fairy tale ending with Steve in diamond armour
Never gonna happen if you don't like her
I'm gon' put her in a mineshaft
Woo!
Don't ever let her out, she got her TNT
She'd blow you up so bad
The creepers would be glad
They wouldn't have to get up (get up)

Her pressure plates are everywhere
I was trying to kill her
But she is one good trapper
I fell into her cave... and BOOM

[Katy Perry:]
So you wanna play with diamonds
Boy, you should know what you're falling for (you should know)
Baby do you dare to do this?
Cause I'm coming at ya with a diamond sword (with a diamond sword)
Are you ready for, ready for (ready for)
A perfect sword, perfect sword (a perfect sword)
Cause once you're in my mine, in my mine (in my mine)
There's no going back
