An overwhelming feeling of purity and perfect peace of the state of mind that is free from craving, anger and other afflictive states while one is a listening to or attending a Heavy Metal concert. The philosophical concept that we all could live in a perfect world if everyone just listened to a little metal music.
To go collect/gather scrap metal (to later take & sell/cash in @ a junk/scrap yard) most of the time, collecting is done during the "grave yard" shift hours.
