The AU is counted if they primarily go by the 1 to 101 structure and have either completed a majority of their soundtrack or still continuing.

AU Soundtracks in Order:
Remix Soundtracks (e.g. Undertale's music redone)
Roleswap Soundtracks (e.g. Underswap)
Atmosphere Change Soundtracks (e.g. Underfell)
Role/World Change Soundtracks (e.g. Recognized Maniacs)
Joke Soundtracks (e.g. Recognized Maniacs)

My UNDERTALE AU Masterlist!
For every UNDERTALE AU I can find on SoundCloud.

Contains COMPLETE, INCOMPLETE, and ONGOING AUs.
We've reached the maximum with 500 tracks! (If some don't get removed)

DISCLAIMER:

Inform me if:
- You want an AU removed.
- An AU isn't in the playlist.

"Once Upon A Time" replacements / equivalents are used.
If there isn't one, the "earliest" track will be used.

I will be using ONE version of a track per AU.
Older / outdated versions will NOT be used.

Organization may be inaccurate. Inform me if I messed up!
Anything below COOL TALE is still unsorted!

Track 001 - Once Upon A Time

UNDERTALE Soundtrack

Once Upon a Time

Not much to say for this one. It was fun experimenting with the composition.

001 - Once Upon A Time

"A long time ago, two races dominated the world:
HUMANS and MONSTERS."
"Then one day, a war has been declared between the two races."
"After a long battle, turns out the humans were victorious."
"They sealed the monsters away with a magic spell."
"A magic spell that makes monsters trapped inside the underground, for a long time."
"Many years, later..."
"MT. SERECH, 200X."
"Rumors said that those who ever climbed the mountain,"
"... Will never come back."

001. A Beginning

In A Land Far Away

"In the past, there was a legend"
"A legend, of HUMANITY and MONSTERKIND"
"MONSTERS, HUMANS, they developed a series of fierceful battles"
"The HUMANS, were victorious"

* Long ago, humans and monsters coexisted in harmony upon the surface of the Earth. 
* Their lives intertwined, they shared laughter, dreams, and the beauty of their world. 
* But peace is a fragile thing, easily shattered by fear and misunderstanding.

* It was an era of prosperity and unity, until the fateful day when tensions between the two races ignited into full-blown conflict. 
* The reasons for war have long been forgotten, buried beneath the weight of history. 
* In the chaos that ensued, the monsters, vastly outnumbered and outmatched, were driven to the brink of extinction.

* Forced to retreat, the monsters found themselves banished to a realm beneath the surface—an underground prison of eternal darkness. 
* Cut off from the sunlit world they once knew, they built a new civilization in the depths, clinging to hope of one day returning to the surface.

* Years turned into decades, decades into centuries, and the surface world forgot about the existence of their former neighbors. 
* Yet, the monsters endured, their spirit unbroken despite the harshness of their new reality.

* And so it was that many years later, fate would once again intertwine the destinies of humans and monsters. 
* On a quiet night, a child, the seventh of its kind, tumbled into the gaping maw that led to the monster's realm...
* A child whose arrival would set into motion events that would change the course of history.

* Little did anyone know that this child's journey into the depths would become a beacon of hope, a chance for reconciliation, and a test of courage and compassion. 
* For in the heart of darkness, where fear and despair lurk, a new story is about to unfold—a tale of friendship, adversity, and the quest for a peace long lost.

* This is the story of Undertale.
