Music Disc (The Wanderer) is a Music Disc added by NuclearCraft. When placed in a Jukebox it will play a MIDI rendition of the Dion song "The Wanderer" (as popularized by the game Fallout 4). It can be crafted by combining any music disc with an ingot of Tough Alloy.
In-game, the disc is simply named "Music Disc". It can be identified by its green label.
