(Creative Parity) Aria Math

At the moment "Aria Math" a track by C418 is only accessible in creative and I feel this ambient soundscape should be implemented in survival mode as well. "Aria Math" has an adventurous feeling to it, it has the sounds of a cave (which are mainly explored in survival). The lot of drum has a damp, dank sound to it (It's mainly the reverb but) a damp sounding track belongs in survival.
