I use to be a metalhead myself. I still listen to heavy metal and hardrock everyday and sometimes classical music. Basically whatever I feel like listening too. I would be one of those people who would defend their favorite genre from so called edm cigarettes and soccer parents who would bash the genre with misconceptions. Like the type of people who think every heavy metal band sings dark depressing songs or screams and makes death growls. They just don't know what real metal is.
Anyway it doesn't matter what the people around you like to listen too. Just listen to what you like to listen too and don't bash the others around you. Almost every Iron Madien song on Youtube has atleast one comment bashing Justin Bieber, One Direction, or whatever is in the current top 40 muscians. Just remember the popular music of today is garbage and in the near future corporations will find a new cash cow. Don't waste your time bashing the song, instead listen to the stuff you like. Also I keep my music on low so I'm not forcing my music on other people.
