To the tune of jingle bells, I believe I have met the four lines requirement. (https://en.m.wikipedia.org/wiki/Jingle_Bells)

Dashing through the front, in an AAT, o'er the clones we go, cackling all the way (hahaha), guns are overheating, barrels glowing bright, what fun it is to ride and sing this slaying song tonight. Jingle droids jingle droids jingle all the way oh what fun it is to ride in an AAT tonight!

Force, wash over me, parum pum pum pum,
Balance I'm told to bring, parum pum pum pum,
A Jedi Knight I'll be, parum pum pum pum,
Obi-wan you'll train me, parum pum pum pum,
Rum pum pum pum, rum pum pum pum.
Vader, i have become, parum pum pum pum,
Palpatine won.

Luke, my baby boy, parum pum pum pum,
Tatooine, raised on a farm , parum pum pum pum,
The Force is strong with you, parum pum pum pum,
And strong with Leia too, parum pum pum pum,
Rum pum pum pum, rum pum pum pum.
Will you save my soul, parum pum pum pum (shall i)
Evil no more

Force, welcome me back parum pum pum pum,
Light and Dark don't look back, parum pum pum pum,
Master and student dead, parum pum pum pum,
And join us Yoda did , parum pum pum pum,
Rum pum pum pum, rum pum pum pum.
My body, pyre burns, parum pum pum pum,
Vader is done.

Here Comes Anakin

Here comes Anakin, here comes Anakin,
Right down Anakin lane
Cody and Rex and all his clone troops
Being the Seps bane
'Nades are flyin', Seps are dyin'
Clankers smashed up just right
Hang your heads and say your prayers
'Cause Anakin comes tonight!

Here comes Anakin, here comes Anakin,
Right down Anakin lane
He's got a ship that's filled with troops
For bringing down the pain
Hear those Seps as they get strangled,
Oh what a beautiful sight
Your troops all fled so cover your head
'Cause Anakin comes tonight!

Here comes Anakin, here comes Anakin,
Right down Anakin lane
He doesn't care if you're rich or poor
He hates you just the same
Anakin knows you're all just rebels
Waiting for a future fight
So fill your hearts with Lifeday dread
'Cause Anakin comes tonight!

Here comes Anakin, here comes Anakin,
Right down Anakin lane
He'll come around when his skin burns up
And he is born again
Peace and justice come to all
If we just follow his might
So lets give thanks to the Lord of Sith
That Vader now comes tonight!

I'm dreaming of a good movie
Just like the ones that used to show
Where Rian screwed up let Abrams brew up
A number IX that doesn't blow.

“Little Trooper Boy” (Parody of “Little Drummer Boy” by Pentatonix)

Come they told me
Pa-ra-pa-pa-pa

A new Sith Lord to see
Pa-ra-pa-pa-pa

Our finest men we bring
Pa-ra-pa-pa-pa

To Serve Lord Vader
Pa-ra-pa-pa-pa
Ra-pa-pa-pa
Ra-pa-pa-pa

So to honor Him
Pa-ra-pa-pa-pa
When we come

Ra-pa-pa-pa
Pa-ra-pa-pa

Lord Vader
Pa-ra-pa-pa-pa
I was a slave boy too
Pa-ra-pa-pa-pa

I have no gifts to bring
Pa-ra-pa-pa-pa
That's fit to give the Sith
Pa-ra-pa-pa-pa
Ra-pa-pa-pa
Ra-pa-pa-pa

Shall I serve for you
Pa-ra-pa-pa-pa
Pa-ra-pa-pa-pa

The Emp’ror nodded
Pa-ra-pa-pa-pa
The Cap. and Sarge kept time
Pa-ra-pa-pa-pa

I shot my gun for Him
Pa-ra-pa-pa-pa
I shot my best for Him
Pa-ra-pa-pa-pa
Ra-pa-pa-pa
Ra-pa-pa-pa

Then He Force-Choked me
Pa-ra-pa-pa-pa
Me and my gun
Oh oh oh oh oh oh oh oh oh

Come they told me
Pa-ra-pa-pa-pa
The new Sith Lord to see
Pa-ra-pa-pa-pa

Me and my gun
Me and my gun
Me and my gun
Me and my gun
Ra-pa-pa-pa

You're a Sith soldier
Choosing your targets
Pick your gun up and dust yourself off and back in the crossfire
You're on the front line
Everyone's dying
You know they're victorious, they're getting closer, this fights over

I had to fix this because I also accidentally submitted the same thing to this event. note to self, Alara. Don't submit when you're tired.

Jolly old Darth Plageius
Lean yourself that way
Please fall off of that tall tall ledge
For my Daddy's sake

I just found out he's my dad
I don't want him to die
Oh no it seems its too late
you tried to make him fry

Falling old Darth Plageuis
I hope you rot in hell
You made my life miserable
Mine and my dad's as well
My mom suffered because of you
So here's our revenge
You won't get a funeral
Because you fell off the ledge

And I was like Padme, Padme, Padme NOOOO!
Like Padme, Padme, Padme NOOOO!
Like Padme, Padme, Padme NOOOO!
I sensed you'd always be mine (mine)
