[NOTE: GRAHHHHHHHHHHHH!!!!! THIS PLAYLIST IS OUTDATED GRAHHHHH!!!]
I will NO LONGER be updating this playlist, as I have a different, more organized way of sorting AUs!
Please check out my NEW Masterlist below!
https://soundcloud.com/brandoneatsair/sets/masterlist-hub

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Older / outdated versions will NOT be used.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!
(Trying to sort everything by naming convention / alphabetically!)

:ORGANIZATION:

UNDERTALE - Base OST - UNDERTALE
"Remix" - Reworked Base OST - UT: Alternate --> Swapped Rhythms: Advanced Reboot
"Sequel/Prequel" AUs - Sequel/Prequel to UT - STARCHILD --> DONTFORGET

[OUTDATED] UNDERTALE AU Masterlist

Here are some Au themes I found when exploring the SoundCloud website. Enjoy.                                   
Rules for this Au Playlist:                                              
1. If there's a new version of the theme that sounds better, that theme will be replaced with the new version.                                                                     
2. If a Au theme haves a motif that similar to that theme, it won't be added to this playlist.                   
3. If an Au theme sounds so bad that it should get a V2, it's added to the bottom Best to Worst themes

Update: I Updated picture because that other one was outdated.

Plants Vs Zombies - LoonBoon (Cover By SeventhVampire)

Graze The Roof

* 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.

*Now you listen here, ya red...uh...whatever it is you are...
*I'm gonna have to ask you kindly to go back inside.
*It ain't time for you to go out into the world yet.
*All sorts of bastards out there who'll wanna cook you well-done.
*Like that HOMER fella.
*These folks ain't right, I'll tell ya what.
*Now I'm a simple man.
*I sell propane, and propane accessories.
*But you do not want to piss me off.
*Now go back inside, or I'll kick your ass till it's three shades redder!

===== DIALOGUE =====
* FRISK - ATK ∞ DEF ∞
* Damn, their determination is too strong.
* Even with the souls they've took, it just makes them even stronger.
* Looks like it's all up to me to save them.
* After all, they went through hell and back just to save the Underground.
* Frisk... I'm returning the favor.
* My ol' partner.

===== NOTES =====
I'd go on a whole spiel about how this idea was outta nowhere but i've pretty much done that song and dance more times than I'd care to admit so imma just say I hope you enjoy this ^-^

This profile contains a select amount of musical work in UTSC from Br1ghtEN between 2018 and 2022. This is not the full extent of their UTSC creations, as a lot of them were previously deleted from Soundcloud and have since been lost to time. Some reuploads may occur in the future.

Br1ghtEN still creates music but is now known as ProduceVGM, and can be found here:
