[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 THIS PLAYLIST IS OUTDATED GRAHHHHH!!!]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Older / outdated versions will NOT be used.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!)

A Quiet Night - Unizone's Underswap Distrust [SCRAPPED]

Art and track by me
Probably the most emotional track I’ve ever made




A bittersweet ending to a story of two brothers fated to loose everyone they ever loved by their own hands 
After winning the battle and breaking the barrier two skeletons watch the sunset as they dust away knowing they had saved the whole underground from and endless cycle of suffering

Yeah, I'm doing this.
Undertale Rearranged is a fun passion project where I attempt to rearrange all 101 tracks of Undertale.

The Door

* ... 
* It's so strange.
* There's a place even deeper than this.
* ... What do you think is down there?
* ... Ha ha ha.
* Are you afraid?
* Don't worry, I won't push you.

41 - Staring Into The Abyss

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

001 - Once Upon A Time

there isnt really any reason for this take to exist other than the fact that i made texas style and to show that the bridge section borrows from this

rm baath take (unfinished)

UNDERSWAP PAPYRUS - Laidback Boneback

* WE HERE AT [Big Shot Enterprises]...
* SINCE THE [Dawn of the] COMPANY...
* HAVE ALWAYS BEEN LOOKING FOR NEW WAYS...

hello - really didnt want my first upload here to be a megalo, but here we are
you could say this is more of a test than an actual update, since ive been away on vacation for over 2 months with a much shittier PC, so i made this using pretty much only FL stock stuff, a bunch of soundfonts and a couple random samples... and my very shitty earphones, so excuse the extremely sloppy mixing - i might come back to this one later and fix some things up
if you were wondering where ive been... well, ive been busy with real life stuff and trying to figure out what the hell i wanna do with said life, but also working on some other unrelated projects and focusing on drawing
if you havent already seen, my account was hacked, which is why im on this account now - i dont really mind, im not big on having a lot of peoples attention on me anyway
im also going to try to not harp on myself too much for uploading megalos if it does happen to become a habit again. they have a certain structure and style thats fun to work with, so if i end up making more, so be it - i dont really care if theyre out of fashion or if theyve "fallen off" if you will
so yea, ill just be here and post whatever i make at whatever pace i make them. thanks for reading, hope you enjoy :)

Welcome to T-SPIN, a series of AUs based on Storyspin and its furtherspun brethren. Follow our protagonist, Oliver, on their adventures throughout each version of the Underground.

T-SPIN Double is based on Spinspin. You can check out the playlist (https://soundcloud.com/t-spins/sets/ts2-ost) or the T-SPIN channel in The Void (https://discord.gg/dPTCQwxUNd) for the most up-to-date versions of the rolelist.

All of the intro sequences -- at least, as far as I've currently decided, this could easily change -- pretty much convey the same information that it does in Undertale. Humans and Monsters live together, war breaks out, the usual.

After unfortunate circumstances took her and her husband's lives, the royal scientists went to work on finding a way to bring her and her husband back. Using dead snails (note: not Monster snails, just boring old regular snails) and Determination, they had managed to bring Toriel back. Now she aimlessly roams the Underground, searching for something that might bring her back fully, as opposed to being trapped in the now undead body of a snail.

[T-SPIN Double] Watching Over You

Check it out on YouTube: https://youtu.be/iZoImTgNto8

===== NOTES =====
Welcome... to T-SPIN! A series of AUs based on Storyspin and its further-spun brethren. Follow our protagonist on the adventures they have through each AU's version of the Underground.

T-SPIN Double is based on Spinspin. You can check out the playlist (https://soundcloud.com/t-spins/sets/ts2-ost) or the T-SPIN channel in the Argenoverse Discord (https://discord.gg/qmtQxwYKfD) for the most up-to-date version of the rolelist including whatever minor roles have been decided on at that time.

Once I have a more expansive plot synopsis for these AUs individually I will put them here (and in future tracks' descriptions), but for now this will have to do.

Mettaton was once King of the Underground, ruling alongside their cousin who was officially moreso the royal advisor, but he treated them like royalty just as much as he treated himself as such. He let this power get to his head a bit and started doing things that mostly benefitted himself. Nothing that'd actually put monsters in direct harm, he wasn't that stupid, but nothing that actually did anything good for them either.

One fateful day, he was overthrown by the people, exiled to the shadier part of the Underground, and the royal advisor was crowned monarch in his place.

Now Mettaton lives in the so-called slums of the Underground. He's managed to find a fairly decent space to live in, a place where he can recharge if necessary (which is very frequently the case given how much power his body drains... if only he had a more energy efficient mode) and where he can lie on the ground feeling like garbage.

Of course, despite his exile, he puts on a smile and his signature flamboyant confidence and acts as though there's nothing wrong! Because why would there be?

Complete sidenote, whenever relevant, thumbnails will also feature character designs now! The old thumbnails will slowly be updated as well, but my priority for the time being is going to be the ones that are being actively uploaded.

Constantly acting as though everything is fine can be very draining, both emotionally and physically -- Mettaton is no exception to that. By the time Oliver shows up at his house, he doesn't really have the energy (literally) to keep it up anymore, being a bit more quiet before inevitably breaking down in front of Oliver.

As Oliver goes to bed to take a quick nap before they continue on their adventure, they can hear Mettaton quietly singing to himself, which slowly puts them to sleep.

[T-SPIN Double] Lullaby

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"

1. Tales Sunken in the Past

* 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.

T-SPIN is a set of Undertale AUs made by Toadie, based on Storyspin and its further-spun brethren, which probably have better names than "Spinspin" and "Triplespin" but none that I can particularly specifically remember.

Each of the three AUs have their own rolelists which can be found in their respective playlists.

You can also check out the Argenoverse server for more information about T-SPIN.
