This song is just pure evil. How evil you may ask? It is so evil that born-again Christian, Dave Mustaine, will no longer play it live. Like most things evil, this song starts off with a soothing, inviting melody. This captures the listener's attention and brings them floating along. This instrumental intro is called "Good Mourning". Now it's time to tell you what this song is about.
"Good Mourning/Black Friday" is about a homicidal killer's descent into a blood-thirsty killing spree. This violent turn of events takes place around the one minute mark as the killer wakes up and goes into a violent fit. This is also where Megadeth shines. Dave's thrash metal is at an all time great, not only on this song, but the entire album. The song continues on a violent thrash as the killer ramps up his kill count.
