This resource pack only remixed some overworld survival tunes, so nothing located outside of minecraft/sounds/music/game.
Remixed music and links:
hal1(Subwoofer Lullaby), by Advait (or feardog, idk)
hal2(Living Mice), by Laura Platt
hal3(Haggstrom), by citrusgastank
piano3(Mice On Venus), by Cleur
left_to_bloom(Left to Bloom), by J. Rivers
infinite_amethyst(Infinite Amethyst), by Lovidove
These are all of the songs I used, and full credit goes to the original creators, especially Call Me Abee, who had multiple songs included.
Nether Pack Coming Soon
