Doesn't Discord remind you so much of Oogie Boogie? Anyway, this is a parody of Oogie Boogie's song from the Nightmare Before Christmas.
I own nothing.
Discord: Well, well, well! What have we here?
Magic of Friendship? Oooooh, I'm really scared!
So YOU'RE the ones Celestia's talking about? HAH!
You're joking. You're joking!
I can't believe my eyes!
You're joking me; you've gotta be!
This must be some disguise!
They're little! They're ponies!
Oh, I don't know which is worse!
Why...I might just split a seam now,
If I don't die laughing first!
When Mr. Discord stops to say,
"Trouble's coming, you see!"
You better pay attention, now,
'Cause I'm Disharmony!
And if you aren't shaking,
There must be something wrong...
'Cause this'll be the last time
You'll hear my chaos song!
Whoa-oh (Woah-oh)
Whoah-oh (Oh-oh)
Woah-oh! (Woah-oh)
I'm the master of mischief!
When, I'm feeling a little antsy,
And I've nothing much to do,
So how 'bout I will cook you all
Into a pony stew?
But wait- there is just one thing
That would make this oh-so-sweet...
Your precious pony princess,
Granite at my feet!
(Woah-oh) Woah-oh
(Woah-oh) Oh-oh-oh-oh
(Woah-oh) Yeahhhh,
I'm the master of mischief!
Twilight Sparkle: Release us now, or you will face
The dire consequences!
Enough with all your silly games
And please come to your senses!
Discord: HAH!
You're joking! You're joking!
I can't believe my ears!
Will someone shut this pony up?!
I'm drowning in my tears!
It's funny! I'm laughing!
You really are too much!
And now, with your permission...
I'm going to do my stuff.
All ponies: W-what are you going to do?
Discord: I'm gonna do the best I can.
Hahahahaha!
Woo-ooh-ooh-ooooh! Yeah!
...
Hah!
Yeah!
Woahhhh...
The sound of chaotic times,
To me, is music in the air!
Cause I'm Discord among you ponies,
And y'know I won't play fair!
It's much more fun, I must admit
When lives are on the line!
Not mine, of course, but yours, old girl...
Now that will be just fine!
Twilight Sparkle: Bring back my friends, or I so swear
You'll suffer for this heinous act!
Discord: Oh honey! You're something!
You put me in a spin!
You aren't comprehending
The position that you're in.
It's hopeless! You're finished!
You're running out of time,
Because I'm Disharmony, and I say...
Equestria... is... MINE.
Hahahahahahahaha!
Well, how did you like it?
