Pretty much back in 2000 when I got into high school, started listening to the "mainstream" metal bands such as Linkin Park, Disturbed, etc. Before that (around 199 I started listening to what my older brothers listened, 80s metal bands and that is why I got into the genre. Going into high school I got swept by the so called mainstream metal a little.
Suprisingly, I don't like metal anymore.

What are
you listening to now?

Do you dislike all metal now? Keep in mind that there's a very wide spectrum of metal, from melodic power metal to stuff that sounds like a dumptruck thrown into a grinder.

I liked elvis a lot when I was a kid, then I wound up "growing out of it". These days power metal, melodic metal, folk metal, etc are at my forefront.
It's rather funny, I used to view bands like iron maiden & helloween as lesser metal & loved the heavy stuff. Now I still like thrash, but not heavier stuff, and I find bands like iron maiden & helloween to be the most preferable.

I actually never got into mainstream music. I basically lived off my parents' collection of 60's music such as the Beatles. I only became aware of it around 2008-09ish but I still never really cared for the newer music.

What about you?

I've liked a few mainstream songs here and there over the years but genarally have always been against that shit. Lucky for me I have six older siblings that showed me alot of good tunes when I was growing up.

I feel sorry for these radio friendly kids these days because the mainstream music now is just pure watered down bubble-gum shit pop music. Its god awful. At least ten years ago there were different genres in mainstream radio but it seems like its one genre now. its like crappy techno pop hip-hop blended coarsley.

Same here. I'll take Smash Mouth or Sugar Ray over today's shit. At least their songs were pretty catchy.
