I was able to add music to this list: "$type": "Vintagestory.API.Client.CaveMusicTrack, VintagestoryAPI", parts: [ { files: ["deepunderground/aquatic drone*"] }, { files: ["deepunderground/bell piano*"] }, { files: ["deepunderground/bells*"] }, { files: ["deepunderground/deep drone*"] }, { files: ["deepunderground/metal bass*"] }, { files: ["deepunderground/piece*"] }, { files: ["deepunderground/ticking*"] } ], stopMusic: true, maxSunlight: 12, But on testing I quickly found out that they actually play some of them at the same time. However when I add in the music like this: "$type": "Vintagestory.API.Client.CaveMusicTrack, VintagestoryAPI", file: "Music", name: "Music", onPlayList: "survival", stopMusic: true, maxSunlight: 12, It just wants to crash the game. (and I've tried it with "min/maxhour" to the same result)
