Trivia

 * When using the virtual tour of Phase 2 Kong Studios, cassette tapes could be collected throughout the building and brought to the studio desk in order to listen to the isolated specific instrumentals for each instrument used in the song. When all tapes are collected and inserted into the mixer in the studio desk room, the complete instrumentals for the song can be heard without vocals.
 * When accessing the previously mentioned virtual tour, it is possible to visit the landfill behind the studio that inspired the song along with the steam whistles that create the sounds used in the song. When played in the correct order, they can create the sounds identical to the ones in the song.
 * The title of this song was originally the name of the album, Demon Days.
