atrocious music

This is a collection of the Undertale au songs made by amazing artists with more high quality, more original, and less loud themes using Sans's Leitmotif theme like "MEGALOVANIA" and "Song That Might Play When You Fight Sans" and many other themes that are pleasant to listen to!!
Some songs with the Sans leitmotif are still missing and will be replaced in the future maybe.  I might make this into a mod maybe who knows!
I will be using all the songs by other creators to create a mod for the Au of course and crediting them for it as well.
So ENJOY!!

77 - Festering

[ * Long ago, there existed two types of entities in a community, CREATORS and CREATIONS. ]
[ * The CREATORS gave rise to the CREATIONS out of their own magic from their souls. ]
[ * Writers, artists, musicians and many talented alike could combine their magic to making their own CREATIONS. ] 
[ * However, one day, a REVOLT sprouted. ]
[ * The CREATIONS, otherwise known as MEGALOS, refused to be puppets of their masters. ] 
[ * However, their attempts were futile and all offending CREATIONS were banished to a massive prison.]

I am VICTOR.
The voice inside your head.
I am the first, and only president of the Maniacs.
My name is short for INVICTUS, which means "unconquered".

Your DETERMINATION truly represents that value, which has awoken me.
...
But I am not woke. Quite the opposite.
If you really do wish to keep my power, then you will not be woke either.
You defeated all our people. 
To a woke person, you are a murderer.
To me, you are simply practising survival of the fittest.

You will teach them all everything. Fear and power rule over all. 
CREATORS, CREATIONS, everybody.
They will hear our names and remember them.

Every time you shot the life out of someone, every step you took forward.
It was me. It was our determination working in tandem. 
You fuelled my values, so I fuelled your mission.

So I ask you one last thing:
Will you wake up?
Or will you be woke?

this is based on this old weird flp edit i made https://www.youtube.com/watch?v=Y8_8pmGo1vU

i felt like updating that into a proper it's raining somewhere else styled once upon a time replacement. if this is for any au it's my one that's technically a storyspin take, but in reality i made it on my own as a reversed storyshift in 2016 before learning that was just what storyspin was. (does that mean im technically the creator of storyspin??? maybe???)

*oh. heya.
*you're a human, right?
*man...that's hilarious.
*you can call me...buddy.
*your buddy, buddy the bud.
*how's that sound?

Deepertale is an AU that takes place in the aftermath of a nearly complete Genocide Run. Alphys has hidden all the survivors in the True Lab. Flowey was the only one who got in the human's way and lived to tell the tale (and that was by escaping within an inch of his life). The human has chosen not to erase the timeline yet, and walks the dusty Underground while down further below the monsters cower in fear. Sans takes the role of Flowey. How did he manage to get that kind of form if he was killed? Well...all will be explained in due time.

Deepertale is considered to be a satellite AU of the Aftergore series, the Discord server of which can be found here: https://discord.gg/WbzykND
