so like. this is definitely gonna be used ingame right. theres literally a cut IN THE SONG... theres a full version out there...

When you're dueling with the knight and you can't survive the fight~~ :3

Why is no one talking about this part it goes so fucking hard

Contains every track in the official OST for chapters 1-4, as well as most of what isn't in the OST but is found in-game.
I've also included as many unused and beta tracks as I could find.

	TRACK ORDER:

The tracks 'pianpian' and 'Concert for you' have been put after 'Piano that may not be played that well' as that's the order they play in in-game.

The trailer theme is at the start because there was no better place to put it.

Most beta, unused, and weird route (snowgrave) tracks have been put after the main OST into their own section to make them less invasive. Think of it as two separate sections of the playlists, or 'routes' if you will.
The exception to this is the Kris piano tracks being in this section (not to be confused with the track labeled 'Kris Piano'). 
These tracks are in the game but don't really fit into the main OST section as it makes the Holiday house sequence too long.

TRACKS NOT INCLUDED:

Power of Spamton older - too similar to the second version; redundant.
Guitar versions of 'TV TIME' and 'MIKE, the BOARD, please!' - can't find them.
Hymns in room with power/mystic band - this is just 'hymn' but with modulation, not worth including.
'Tinnitus' (ch4 weird route ringing) - can't find it.
'tv_results_screen' - can't find it.

If I didn't include something or the track order is wrong feel free to message me about it.

DELTARUNE Chapter 3 UST - m_TV.ogg (Mike)

An unused track for Deltarune’s Chapter 3!

“Earlier, we were considering having a stealth-focused section in the game where you would slowly, slowly sneak around certain areas.

After developing some concepts, we realized a mechanic which basically just makes you move slower isn't necessarily fun.

So, we didn't do that...” - Toby Fox

Sneaky Situation

"Apparently this was the first concept I came up with for Spamton's battle theme. To be honest, I have absolutely no memory of this. When I found it in my files I was quite surprised. (Maybe Spamton made it himself...)

By the way, originally I was planning to have Spamton's intro song, "HEY EVERY    !", also be his shop theme. It was planned that it would slowly drop in pitch the longer you stayed in the shop until it was unrecognizable. But, that ultimately did not match the tone of the dialogue, so I ended up using Dialtone for that." - Toby Fox

Spamton Battle Forgotten

"I think this is my favorite of the unfinished tracks... At least, it's the one I listened to the most when I was working on the game.

Back when Queen looked more intimidating, I wanted to use this as her boss theme. Personally I still really like it, and I even wanted to try to use it for Berdly's battle instead... but the issue was that it just didn't match either of the theme melodies I had already created for those characters.

Bizarrely, I seem to have made this after already making her theme song, as an early version of her theme song is inside of the project file.

1:30 onward (piano only) is totally unfinished." - Toby Fox

Queen Battle Original

The song used in the Deltarune Chapters 1-4 trailer!! Notably a final version of the song heard here: https://soundcloud.com/user-818829001/game-main-theme-piano-sketch
(Note: As of now, there is no rip of the song in the trailer without it's sound effects! If we manage to get that, I will upload it as it's own version <3)

hee hoo bannan

I upload game tracks and create organised playlists. 
If a playlist is missing something, isn't organised, or doesn't even exist, I make my own. If I can't find the tracks I want, I upload them myself. If a track isn't good enough or I think I can do better, I use audacity to make my own version.

Out of uploads, planning on getting next pro for unlimited uploads.
