Known issue: discs being mono leads to directional placement and I'll probably remove them compltely next update
Added chance for alt. game (mountain) music to be played in the cave biomes at a low probability, due to their now even higher density. Always a work in progress and a personal take on how music should be distributed so I'll keep playing around with this.
