Download the Valve intro music (aka Hazardous Environments) and replace the file path of soundFile with the path to your file.
Download Vague Voices and replace the file path of soundFile2 with the path to your file.
Download this song: https://www.youtube.com/watch?v=pQRNx3xqHwQ and replace guitar with the path to your file.
I reccomend https://youtubemp3free.com/en/ to download all of these.
