“I will put my iPod on max volume as a tool to suppress fear if needed. I might just put Lux Aeterna by Clint Mansell on repeat as it is an incredibly powerful song," Breivik wrote.
Witnesses said that the the Norwegian slayer Breivik was 'wearing a headset" as he calmly fired on his unarmed targets, as reported by the Daily Mail.
