well teenager taste is stereotypical music that only appeals to teens, not music that is going to last through the ages.
and yeah, imo dadrock is a form of angsty "oh im so against the grain of society! fight the power" teen that you tend to see nowadays - kids who are like, "forget the radio man"
1. You don't know what's going to last throughout the ages. Stuff that's popular now may fade away as a simple fad would, and not so popular stuff may become revered classics in 50 or so years by following generations.
2. Personally I see it as "forget top 40 and hot hits stations"
Classic rock will stay classic, as the name implies. Some are overrated, like the Beatles I do agree. Also ew Glam Rock/metal. (/opinion)
Well yeah, you're just sooo metal
I guess I was being a bit self centered with that quote. Also, sorry for having a preferred genre. I don't like stuff like Lamb of God and Five Finger Death Punch which is over simplified and based on blast beats and heavy guitar tones alone.
