Jevil didn't have a playlist for his songs yet, so I went ahead and organized one!

If you haven't already, be sure to check out and follow him @jester-devil!
He's made some amazing tracks so far :D

(And thanks a bunch to the creator for the awesome content! Best wishes in completing the rest of the OST!)

JEVIL DELTARUNE IMPRISONED OST

My top 5 versions of Lantern.
While my Undertale lists usually are Top 10s, Deltarune's smaller soundtrack and smaller pool of AUs to choose from (along with existing for less time) means that these lists are Top 5s instead. 
Note that despite Soundcloud's numbering system, the #5 pick is actually the one below the original, and the #1 pick is at the bottom. That way it functions like a countdown.

Some rules apply as always:
1. The song has to be for an AU.
2. Covers and takes are allowed, remixes are not.
3. Only one entry per AU. For example, a song and a cover of that same song or alternate version for the same AU could not both be there.
4. Any variations of "!Deltaswap" (or !Deltafell or whatever) all count as the base AU (i.e. Deltaswap). (Something like Deltarune: Switching Suits, however, could coexist on the list)

Slick's Top 5 AU Lanterns

*UEE HEE HEE!
*WELCOME VISITORS, VISITORS!
*WHAT FUN! HOW MAY I HELP YOU ON YOUR WAY?

This is the "Lantern" replacement

This is a Deltaswap take of mine and it is not for your AU. Please do not claim it as yours, although you are allowed to extend this song, provided you give credit to the original creator. Ask beforehand.

Introducing "PROSEMOOR". A complicated opposite of Deltarune itself. It's named that way instead of an anagram of Underswap or simply Deltaswap. The relevant swaps for now are listed below:
• Asriel - Kris
• Alphys - Toriel
• Noelle - Susie
• Rudy - Asgore
• Frisk - Ralsei
• King - Lancer
• Rabbick - Rudinn
• Bloxer - Hathy
• Seam - Jevil
• Puzzle Guy - Clover
• Starwalker Bird - Scissor Dancer
• Ponman - Jigsawry
• Malius - Top Chef

• Empty Town - Card Castle
• Scarlet Forest - Field of Hopes and Dreams
• The Cliff - The Great Board
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Asriel returns to his hometown after a long school trip. He's found sleeping in a school bus when it finally arrives. Alphys has to wake him up and escorts him back to Toriel by a car. On the way home, a bunch of people happily welcome his homecoming.

-THE WORLD REVOLVING

Whether Deltaswap should exist or not at the moment. In the end, this is just a fun little project I'm making.

Lantern

[Chapter 1] Sparks

(Your crew is approaching a worn out, barn-like structure. The plate beside the entrance says "SHOP" in a pretty fancy font. Well, you have enough money collected, why not pay a visit? You enter the construction.)
(Despite the appearance of the outside, the inside is very elegantly made. There is a lot of antiquarian objects standing on shelves, big and small boxes laying across the floor, which are decorated with eye-catching little statues, fashion subjects and other such charms. You know it's not useful for your adventure, but it is still on your mind how one can collect so much accessories and such. A counter stands in front of you, there is an old, elegant person in a coat sitting behind it, awaiting your arrival. They've specifically focused on Ralsei.)

(Ralsei) * Long time no see, Mr. Seam.
(Seam) * Well well well! If it isn't my fluffy friend!
(Ralsei) * Guys, this is Seam, they're an old friend of mine.
(Seam) * I see you have brought to me some friends...
Do my eyes deceive me? Is that lightners standing before me?
(Susie) * My name is Susie, and this is Kris.
(Kris) * Nice to meet ya, Seam.
(Seam) * After so long... we finally see each other again...
And we're finally speaking one to other like the friends we used to be...
Life is truly a blessing, even if it's soon to end.
(Ralsei) * Actually, we are on an important mission.
We have decided to save the world ourselves and banish the curse.
Please do not be alarmed, no one will be harmed in the process.
(Seam) * So, the time is finally coming, huh?
Well, not that I mind. In fact, I could be of use to you bunch.
Trust me, some of these tools are of great use.

(Seam) Choose what you like, young ones.
