Metal isn't the only genre to focus on sound, obviously. That's why it's called music.
For example, I dislike Jazz - but if I were to make a statement like "Jazz requires no skill" it would be a bit ignorant.

Don't confuse your tastes with an artist's skill.

Skill? Its fucking auto-tuned. However, this guy is decent, ill give you that. No auto-tune here.

There are still voice modification, pedals, etc... used in Metal. They do studio recording too.
The skill I was referring to wasn't his singing, but the dancing. Either way, Metal does the same whether you like it or not.
