I'm using the song Circus by Brittany Spears for this one! The character being... Piper!

Charmspeak - Piper McLean

There's only two types of people in the world
The ones with charmspeak, and ones without
Well baby my voice is kinda powerful
I'll tell you what to do, you're gonna do it (oh, oh)
I'm like the ringleader
I call the shots (call the shots)
I'm like your master
And you're my slave (you're my slave)
When I speak pretty nice
I feel the adrenaline moving through my veins (hah, hah, hah)
Spotlight on me and I'm ready to break (hah, hah, hah)
I'm like a master, you always do what I say(hah, hah, hah)
Better be ready, I know that you can hear me (hah, hah, hah)
All ears hear me in the center of the room
Cause I have charmspeak (ah, ah, ah, ah, ah, ah)
When I use that voice, monsters gonna die
Cause I have charmspeak (ah, ah, ah, ah, ah, ah)
Don't stand there watching me, follow me
Show me what you can do
Monsters all die, we can make this battle ground Dusty
Cause I have charmspeak (ah, ah, ah, ah, ah, ah, ha, ha, ha, ha, ho, ho, ho)
There's only two types of guys out there,
Ones that can hang with me, and ones that are scared
So baby I hope that you came prepared
I run a tight ship, so beware
I'm like a ring leader, I call the shots
I'm like a real master,
When I use my voice you
Spotlight on me and I'm ready to break (hah, hah, hah)
I'm like a master, you always do what I say(hah, hah, hah)
Better be ready, I know that you can hear me (hah, hah, hah)
All ears hear me in the center of the room
Cause I have charmspeak (ah, ah, ah, ah, ah, ah)
When I use that voice, monsters gonna die
Cause I have charmspeak (ah, ah, ah, ah, ah, ah)
Don't stand there watching me, follow me
Show me what you can do
Monsters all die, we can make this battle ground dusty
Cause I have charmspeak (ah, ah, ah, ah, ah, ah, ha, ha, ha, ha, ho, ho, ho)
Let's go(ah, ah, ah, ah, ah, ah)
Do as I say now(ah, ah, ah, ah, ah, ah)
I'm running this
Yeah, like what?
I feel the adrenaline moving through my veins (hah, hah, hah)
Spotlight on me and I'm ready to break (hah, hah, hah)
I'm like a master, you always do what I say(hah, hah, hah)
Better be ready, I know that you can hear me (hah, hah, hah)
All ears hear me in the center of the room
Cause I have charmspeak (ah, ah, ah, ah, ah, ah)
When I use that voice, monsters gonna die
Cause I have charmspeak (ah, ah, ah, ah, ah, ah)
Don't stand there watching me, follow me
Show me what you can do
Monsters all die, we can make this battle ground Dusty
Cause I have charmspeak (ah, ah, ah, ah, ah, ah, ha, ha, ha, ha, ho, ho, ho)
Spotlight on me and I'm ready to break (hah, hah, hah)
I'm like a master, you always do what I say(hah, hah, hah)
Better be ready, I know that you can hear me (hah, hah, hah)
All ears hear me in the center of the room
Cause I have charmspeak (ah, ah, ah, ah, ah, ah)
When I use that voice, monsters gonna die
Cause I have charmspeak (ah, ah, ah, ah, ah, ah)
Don't stand there watching me, follow me
Show me what you can do
Monsters all die, we can make this battle ground Dusty
Cause I have charmspeak (ah, ah, ah, ah, ah, ah, ha, ha, ha, ha, ho, ho, ho)

And the original song is...

There's only two types of people in the world
The ones that entertain, and the ones that observe
Well baby I'm a put-on-a-show kinda girl
Don't like the backseat, gotta be first (oh, oh)
I'm like the ringleader
I call the shots (call the shots)
I'm like a firecracker
I make it hot (make it hot)
When I put on a show
I feel the adrenaline moving through my veins (hah, hah, hah)
Spotlight on me and I'm ready to break (hah, hah, hah)
I'm like a performer, the dancefloor is my stage (hah, hah, hah)
Better be ready, hope that ya feel the same (hah, hah, hah)
All the eyes on me in the center of the ring
Just like a circus (ah, ah, ah, ah, ah, ah)
When I crack that whip, everybody gonna trip
Just like a circus (ah, ah, ah, ah, ah, ah)
Don't stand there watching me, follow me
Show me what you can do
Everybody let go, we can make a dancefloor
Just like a circus (ah, ah, ah, ah, ah, ah, ha, ha, ha, ha, ho, ho, ho)
There's only two types of guys out there,
Ones that can hang with me, and ones that are scared
So baby I hope that you came prepared

Just like a circus (ah, ah, ah, ah, ah, ah, ha, ha, ha, ha, ho, ho, ho)
Let's go(ah, ah, ah, ah, ah, ah)
Let me see what you can do(ah, ah, ah, ah, ah, ah)
