A playlist inspired by underswap 2022. Considering that only a couple of tracks were created for this au, I decided to create a headcanon version for ost on it.

underswap 2.0 (underswap 2022?)

Finally, here it is. The last piece of my 400 followers special, a part 2 to my Unwavering Persistence cover! These songs ended up being a tribute to CD as well as satisfying my desire to covering the OST. Once again, thank you for 400 followers, it means so much to me. Unwavering Persistence by @bdvaughn, Collateral Damage by @madd4punk and the absolutely fantastic art by @user-123274983 (https://malt-1.tumblr.com/). I've got several songs in the backlog, so keep an eye out for them!

* that creep never stops showing up, does it?
* every time i check this place…
* that bot's always just standing there.
* makes me wonder what they’re up t-
* …
* oh…
* heh. that’s hilarious.
* next thing i know, a human falls down.
* you alright, kid?
* seems like you've had quite an event.
* name’s sans. sans the skeleton.
* i’m kind of a well-known figure at the flooded city.
* but i also take care of this old factory.
* by the way…
* i’m actually on a maintenance run right now…
* but it seems like your arrival’s an interesting case.
* why don’t you come with me?
* don’t worry, i got no *bone* to pick with you.
* i’ll gladly guide you over to my place.
* it’s got a cozy bed, some nice food...
* how’s that sound?

Sans takes the role of Toriel. He’s well-known among monsters in the Flooded City for his jokes and laid-back attitude. He also keeps watch over the city’s Old Factory (the Ruins replacement), because some monsters have been hanging around there in refuge from the rain and he wants to make sure everyone’s safe.

Speaking of areas, in this AU, areas swap in two ways: season-wise and aesthetics/style-wise. Here, the Ruins replacement (Old Factory/Flooded City) swaps seasons with Waterfall (Fall <> Spring), but swaps aesthetics with CORE (ruins <> factory).

*(There's a festive winter wonderland all around me.)
*(Such...joy...it fills me with...determination.)
*(Interesting. Very interesting.)

Shipwrecked is a roleshift AU that makes role changes based on popular ships. These are not necessarily ships that we believe in, just ones that have some popularity within the fandom.
I'd classify the AU as taking itself half-seriously. It legitimately has its own style and ideas, but we might not do other stuff for it and it acknowledges how silly its own premise is.
The AU details a timeline after a botched reset by Asriel, in which he gets to be the protagonist, but no one remembers him. Not even his parents.
Along with the ship swaps, there are also some miscellaneous other changes just for the fun of it. For example, the Ruins are styled after Snowdin.

UNDERSWAP (2022) is simply a modern version of well... Underswap. This is by no means related to my personal interpretation of Underswap and will not plan to release the full soundtrack, but will release the tracks occasionally (mostly for the unique role choices) like "DELTASWAP". In this case mainly, Memoryhead, the unknown amalgamate, swaps with Flowey the flower!

Junnboi!UNDERSWAP is my take on the UNDERSWAP AU.
After typing in the name "Frisk", you were expecting to play Hard Mode, right? Well, something's wrong. As the screen fades in, to your surprise you're playing as Chara instead. Everything feels different, yet familiar...

*Let me tell you a story about a boy who wanted to feel the sunshine.
*But first, I will tell you a history nobody has ever told to anyone before.
*Once upon a time, two races coexisted on EARTH to preserve peace and harmony: HUMANS and MONSTERS
*But... unfortunately, that did not last long.
*The HUMANS wanted power, both races waged war against each other.
*Ultimately, the HUMANS won the war, consequently sealing the MONSTERS from the face of EARTH using a magic spell, the BARRIER.
*Which no one can cross over to the surface.
*And everyone is prohibited to mountaineer MT. Ebott... or else, no hope to return.

*MT. Ebott 201X... (camera pans from the mountain to the castle in the underground)
*The Underground, 201X

*Ah, this is where I am going to tell you that story.
*The boy wondered if someday... he could be free from the eternal imprisonment.
*Therefore, he always came to the Ruins to gaze the light above.

You still have no idea who I am... Ok some things about me, just a really busy 17 year-old guy who's spontaneously producing au tracks. I take requests ocassionally or when i have more free time. i work on many aus (including someone's au) and several UT fangames. I make roleswap au tracks a lot more than crossover ones. I mostly make death by glamours, battle against a true heroes, heartaches, and asgores because those are my favorites and really fun to make.

And here's my discord: MoonStriker#0730

QnA:

Q: Do you have any AU?
A: Yeah, I have: Rolled Cycle (Swapspin), Last Hope, and Underswitched. "Will I make songs for one of theses aus?" Someday, yeah. 
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Q: Can I use your musics for my au?
A: Sure! If the description of the certain music says that, then yes! I'm wary about Deltarune aus, though.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Q: Do you have any song project?
A: I consider "Chara and Asriel swap" to be my primary music project. There's more such as "Chaos Kings" and "Doused Flames". Upcoming project might be "Toriel and Asriel Swap" or "Mettaton and Asgore Swap". I'm not sure, but you can decide which one too based on what you're interested with.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Q: Do you take request?
A: Yes, but that depends or it'll take some time to actually do it.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Q: What is your favorite UT music?
A: For battle theme: Battle against a True Hero goes to number one! Death by Glamour goes to second! And finally... ASGORE goes to third! Last but not least... Heartache or Spear of Justice? I don't know, both are on-par to me =P As for area theme, Waterfall and Another Medium for the win!
