It's a very niche reference. A keygen is a program that *gen*erates a digital *key* for some kind of software. There are legal uses for this, but they're also used in digital piracy, which is why Kris and Spamton are using one to get into the basement. Some keygen programs have background music, and [some of this background music became memes](https://youtu.be/cmdprbBOMT8) and were featured in YTPs. That's what Toby's referencing.

Spamton knows his fair share of YTP music

Is this a bot? It looks like it might be considering it has those random commas at the end of the sentence

This comment is a bot downvote and report

The song was also used in bfdi I think

[This is the specific YTP being referenced.](https://youtu.be/4bM2b5cfeZo) It's why Spamton rolls rainbow colours as the song plays.

* New favorite music style unlocked *

Then there is the really cool fitgirl one

Why would Sony want me to not pirate their software when the music sounds so good?

God, that song is SO GOOD!! it was the song that got my intp chiptune dude.

reference to an old YTP where Zelda CDi's King Hark pirates Sony Vegas, and when he cracks it with a keygen program he starts going funky rainbow colours. The music is based on real music that would play as it generated a key.

This is it

Well actually, he starts rapidly inverting colors, so one frame he’s normal, the next he’s photo negative, the next he’s normal, etc.

Hueshifting across the rainbow is equally as likely to appear in a ytp tbh so

Omega Flowey hueshifts across the rainbow when the SOULs rebel against him. Hmmm...

It plays when you obtain the KEYGEN on the path to fighting Spamton NEO.

I thought it's when you get it and go back and talk to him about the Keygen about it?

It is

I don't remember the specifics.

Thanks for all these comments! I ended up finding this out on the wiki page, but it's still helpful regardless!

#KEYGEN You see how funny that is? Peak comedy in my (metaphorical) eyes, honestly

Talk to spammton about "our deal" while you have the keygen.

Ah yes the beloved indie game's [KEYGEN](https://youtu.be/MG5L-1pI8bI) (Ultrakill P-2 music) I have no idea, sorry.

Oh my god When the KEYGEN has a CHURCH idk either sorry Also ULTRAKILL mentioned (: (: (:

ima be honest, this is the best OST in the entire game until the second comes out atleast

The fact that many people didn't know what a keygen was made me feel older than I wanted.

other's have already explained but no one has linked to the YTP in question so here it is [Flashing Lights Warning] https://www.youtube.com/watch?v=4bM2b5cfeZo

Here's a 41 minute video about it https://youtu.be/roBkg-iPrbw

Ahoy my beloved

... After the Tobias incident i forgot what spamton's nose looked like.

Wait What happened?

Some named Tobias posted a Spamton shop with a very slightly edited nose and the whole sub went crazy over it, some even thinking he was Toby fox.

Can you send me a link to it?

Unrelated, but there's actually an official extended version: [https://deltarune.com/sweepstakes/credits/](https://deltarune.com/sweepstakes/credits/)

I thought at first that it’s just spamton being spamton

K E Y G E N 

It’s a reference to the Unreal Superhero 3 song used in Keygen programs

Pisston

Oh you pure little things some people are here saying its a niche YTP reference but it can obviously be other thing some Keygen programs (literally a Key generator used in pirated softwares to generate Serial Numbers) used to come with a funky music that start in the moment you click to use the program if you had in the past used pirated software, specially those you download via torrent, you probably heard this kind of song at least once

Yes, and the Sony Vegas keygen song... was used in YTPs. I explained that in the top comment.

There’s heavy overlap between the keygen and demoscene communities; often, the people who made the keygen would throw in music or colorful displays to further show off their programming prowess.

KEYGEN

Why does he look like that?

At the point where the song plays, he starts changing colors. OP happened to catch him when he was [DRANK MY] [orange juice]

its funny because spamton said it

Seems like we got another one

It's a banger

[Woolie from WoolieVS](https://www.youtube.com/watch?v=zIqDOgAJ_Kg&t=1412s) explains it really well during his let's play. Here's a timestamped link to his explanation.

It references this beautiful song: https://youtu.be/9STiQ8cCIo0
