I have turned many of my male friends into metalheads.
One was a bible thumping Jars of Clay fan,
now he listens to death, black, traditional, thrash and punk.
I never forced him to convert, he was just no longer sheltered musically.
Another friend of mine loved Korn, Limp Bizkit, and Slipknot.
He now likes Clutch, LOG, Slayer, KSE, Death, Iron Maiden, Judas Priest, and Gojira to name a few.
I have turned many people onto Clutch.
