Metal is a loved genre among millions of people. But is it really that good? Well, the simple answer here is no. It's not. Every genre and sub-sub-sub-sub genre (yeah they're that pretentious they have that many genres) may sound different, but inside those genres all the bands sounds almost exactly the same. Dealing with the same riffs, lyrics and vocal styles.
Take Death Metal for example. It's just some really low riffs and some deep growls with lyrics about death and killing people. No band has ever changed this structure in all the years it has existed. Metal has no innovation.
Black metal, thrash metal, progressive metal, etc all suffer from this same problem. Discuss on whether you agree or disagree with me.
Again, let me make it clear I'm not saying all metal sounds the same, I'm saying all metal in their respective sub genres sound the same.
Let it be noted that I don't hate metal. I find a few select bands to be okay. I classify it as real music and I respect everyones opinion.
Here's influential metal at its finest.
Here's some horrible copies and rip offs.
It's literally just noise.
