Navigate to the ost_vol1 folder in the game directory, on Windows this is located here:

• C:\Program Files (x86)\Steam\steamapps\common\VoxelTycoon\Content\base\ost_vol1

Your music needs to be copied into this location and it must be OGG format.

Edit the ost_vol1.playlist file in a text editor, below is the default file.

The options available are:

• Interlude: Specifies the time interval between songs in seconds
• Random: Specifies if the songs are played in random order
  • Values: true/false
• Tracks: An array that contain all songs in .ogg format
  • The path must contain the base folder ( base in this case ) and the name of the file
  • The filenames must be lowercase in the file, their case format is irrelevant in the actual directory
