My parents hated it when I watched MTV and would make me change it every time they saw me watching it. When I was around 12 my dad forbid me from buying the Crow soundtrack so I bought it that weekend. That CD introduced me to Pantera, Stone Temple Pilots, Rage against the Machine and alot of other bands.
I was listening to Nirvana and Metallica before that, but he never really said anything. I think it's because he secretly liked them
