Super lightweight resource pack that brings back the nostalgia for me playing Minecraft in 2022-2023. It removes all background music from Minecraft 1.20 and newer, leaving only the music present in 1.19 and before. Works with C4Music (not required though) and is based off of and inspired by Acclimate.
Originally, this pack only included up to the Caves & Cliffs soundtrack, but I realized that part of the Minecraft nostalgia for me includes The Wild Update and its songs. So I added them and renamed this pack accordingly (it was previously "Cliffs&Caves - C4Music addon").
I would definitely recommend installing C4Music alongside this pack, as C4Music brings back all of C418's songs Mojang removed from the game, plus a couple songs from Volume Alpha and Volume Beta that weren't actually added to the game. If you use C4Music, make sure this pack is above C4Music in your resource pack load order. Also, I removed the C418 songs added by C4Music that aren't from Minecraft Volume Alpha/Beta and weren't made for Minecraft specifically.
Little side note: This pack relies on the music built into Minecraft. That's why it requires at least Minecraft 1.19.
Download it from the Modrinth page. Then put the downloaded ZIP in .minecraft/resourcepacks (vanilla launcher) or the resourcepacks directory of your game's profile (other launchers like Prism, Modrinth, etc). Releases are also available on Github.
