Soundtracks
World of Kirbycraft uses a "soundtrack" system; There are three soundtracks in the game that can be switched between in real time by changing Options (F4) > Sound > Soundtrack.

The three soundtracks are Normal, MIDI, and Chiptune; Normal is the intended soundtrack for World of Kirbycraft, containing WAV/OGG/IT songs, usually original compositions for the game, though a couple may be copyrighted songs like Famous by Puddle of Mudd, which may cause copyright problems on websites like YouTube. This soundtrack is the default, so change to another soundtrack or mute the music to avoid potential copyright strikes.

MIDI is the second soundtrack, which as its name suggests is entirely comprised of songs in MIDI format only. Like with the normal soundtrack, the MIDIs here are mainly original compositions, usually made by Xane Myers, though a few are from video games, though not all video game songs were remade in MIDI. If a song is copyrighted, the MIDI soundtrack will play an alternate song, usually from a videogame.

The last soundtrack is comprised of chiptune versions of World of Kirbycraft's original songs made using Famitracker with the VRC6 expansion chip. This soundtrack is louder than the normal soundtrack, so adjusting the volume is suggested before changing to this soundtrack. The file the chiptune soundtrack gets its music from is located in wok_extra_lag.pk3 > Music > NESMUSIC.nsf.

The "Slot" System
Similar to Sonic Robo Blast 2, World of Kirbycraft handles music differently than the game it's based on, Doom, instead opting for a "slot" system. Each song in World of Kirbycraft is associated with a number, like 1 is "The Nightlife". To change the music, ACS script 254 is given a number which, depending on your soundtrack, will choose an internal music "lump" within that soundtrack's array. You can hear these songs in-game by bringing down the console (~) then typing puke 254 #, where # is a music ID. If you type an unknown ID, you'll get an error about a song called "PIC_NONE" or "CITYENT2" not existing.
