So, I had this is my mind for a while, and then I decided to make this.
However, I have no idea who's Asgore in Taletwelve, so let me know if you know who's Asgore in it.

Say Hi! [A Howdy Stranger Megalolazing]

A "Menu" replacement for Underswitched

Underswitched is created by me
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Underswitched is another au arises to be a "role-switching" type. Here, Asgore replaces Asriel and Toriel replaces Chara. Oh! And the "unused human" replaces Frisk. More info coming soon... Stay tuned for more USwitched content!

It's all led up to this.
Issue is, 𝐭𝐡𝐢𝐬 𝐝𝐚𝐫𝐧 𝐭𝐡𝐢𝐧𝐠 𝐢𝐬 𝐰𝐞𝐞𝐤𝐬 𝐥𝐚𝐭𝐞.
(Already planned to post this 7/27/20. Darn it.)
(Due to... complications. I had this made months ahead of time, with development beginning 3/20/20! And yet, the worst happened.)

But, uh, Happy (Late) Birthday, L____ (a wonderful IRL friend of mine)!
And... thank you for all you've done for me.
As a good friend. As someone who has helped me through rough times.
I, thank you, sincerely.
And I'm sorry that this is wayyy late, despite all I could do. Heh.
Good day to all.

[L̶a̶t̶e̶ Birthday Gift]- One For All (Cover)

"Heya."
"I'm Papyrus! Papyrus the skeleton."
"... Doesn't really have the same ring to it as it does with Sans-"
"ANYWAYS!!!"
"Welcome to hell. Enjoy your stay."
"The people here suck."
"No, seriously..."

This is actually my effort at completing one of Zeroh's scrapped songs. He gave me permission, of course. Furthermore, he made the thumbnail! He did more for this than me overall but oh well-

RUN, RUN, RUN!!!

I got FL Studio! Hopefully this isn't too bad for my first attempt at using it. I wanted to give it a similar vibe to the Song That Might Play When You Fight Sans, while making it more upbeat and less intense. I have no thumbnail at present, but I pictured the very old TS!Underswap Sans design while making this. Enjoy!

Also, please don't slaughter me for mixing SNES, GBA, and Sega Genesis instruments.

Underswap - SANS'S VERY COOL FIGHT SONG!!!

* ...
* so y're the legendary fartmaster, eh?
* c'mon, kid.
* y' know that codeword can't change things anymore.

I love the original song. It's so good.
I love Laucanosa's parts of this song. They were all very cool.
My parts? Uh...
We can gloss over that.

Try and guess who did what parts. It's not difficult if you know our styles.

This was a collab with Laucanosa, who set the vibe for the whole song. They also did the thumbnail. They can be found here:

The Clash is by legendaryfartmaster, who definitely isn't Wicher, and can be found here:

Howdy, everyone! I wasn't lying when I said I would be coming back from my long hiatus. Aftergore is a pretty big AU currently, so I thought I'd contribute some love and support for the AU. This is my 10th song cover, as well as my first ever "Toriel" track (specifically, a track that revolves around Toriel herself, not a Toriel-styled track like "His Hopes"), disregarding an unreleased "Fallen Down (Reprise)" cover. Enjoy!

A quote from Slick Sliver:
"Aftergore is a series of AUs taking place after Undertale's neutral endings, in which a new human enters in Frisk's wake.
Aftergore I, the Incomplete/Flawed Pacifist ending, details an ending in which everyone (except for Asgore) was spared and befriended. Toriel has taken her ex-husband's place, ruling the Underground with both strictness and kindness. Humans are to be treated not as enemies, but as friends.

Toriel takes the role of Asgore. However, she does not hide away in the castle for the whole adventure. You can find her at her very own school in Snowdin Town, where she's happy to see you! Surprised? Remember, her policy is to treat fallen humans not as enemies, but as friends!
She wouldn't ever do anything to hurt you...right?"

[Aftergore I] Boss Monster (10th Song Cover Special)

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!
