As a 8 year old, I was introduced to jihadi music in a casette by a local imam.
So I would get my casette player, lay on the grass in a park, play this and close my eyes, and as little Jim, I would fantasize an army of jihadis behind me, and then I commend them to charge at a population of Jews (as I told they were evil by the imam)
These jihad fantasies got me thru the worst times of my life.
