Minecraft wiki entry for Rube_Goldberg_machine, associated text: You can add music to your Rube Goldberg devices by using note blocks. Even other blocks in Minecraft that make noises, such as droppers, can sound quite melodic when mixed in with note blocks. They could contain stuff in them to jump right into the N-ice items! trick. Also, shot arrows make a whole different sound, so you can leap straight into the "Oh, shoot" technique. You could go with the classic "Worth a Shot" technique. Keep in mind pistons are musical as well (carry on into Pistone), and so are doors (release the zombie into a maze!)
