Dave Mustaine has issued the following update: "I am so stoked to see all of the positive comments about "Headcrusher", since this was the last song that we wrote on the record. You see Shawn had this song and there were parts that I took out and wrote the rest of the song to, and there you have it. The concept is about the torture device, the most horrific allegedly, and the image is of a person subject to the nauseating results of a "head crushing."
