Ok. So if it's not called Musical Intelligence. How should we call it?
I was referring to the fact that some people, like me, have grown to appreciate music better. When I first listenned to Death Metal I didn't like it and made a judgemental statement about this genre, claiming it was random noise with a guy puking in a microphone. I then learned to listen to it, properly. In that way, I got better at listenning to music. Let's not call it Musical Intelligence. You are right, that is not the proper word for it.
But when I was talking about these Melodic Metal fans, who never get to appreciate anything else in Metal. I was not talking about those who listenned and didn't like it. Cause there is obviously two different type of Melodic Metal fans. The close-minded ones, who listenned to very little metal with harsh vocals and there are those who really just don't like the most agressive genres of metal and like the clean vocals better for different reasons. Like AniMetal said, he always was more into Power Metal and the such, not because he was close-minded, but because that was just what he liked the most. But there is a lot of people, who simply do not want to try and listen to it. They don't try to understand the music and how the vocals are coherent in the music. Nev said it's irrelevant. But I'm pretty sure I did start liking growls when I understood that they fit perfectly with the music. So when you understand that it's coherent with the music, then you can start liking it. Like I said earlier, thrash metal vocals really are not my type, but I'm slowly getting into Thrash Metal, and I'm starting to like these vocals.
There are exceptions. I'm not saying each and every single vocalist is doing a good job. Sometimes there will be bad vocalists, guys who fuck your brains with their vocals, but saying a whole type of vocals is innapropriate, is far from saying "this guy doesn't know how to sing".
