Ok, I'll try to explain my point using morality and a little but of philosophy.
Many people don't realize how difficult it actually is to come to the conclusion about moral relativism. On the surface, it seems like an easy choice, but when you examine the effects it has on society, they kinda suck. In saying that morals are not universal, we can't technically punish the man who killed and raped his entire family because "Who's to say he didn't think what he was doing was moral? Who are we to judge?"
Even if you do believe in moral relativism, what it really does is shrink to moral nihilism and all ethics becomes null and void. So in order to fix it, one needs to understand that we all have moral relativism, but act in such a way that most of society would find you to be a "moral" character.
The same can be said for what I'm talking about. In my personal view, everything in music is subjective. When I say everything, I don't mean everything. That would be stupid. Wait for Sleep is shorter than ACOS, but that's not what I'm getting at. Better? More technical? More soulful? We don't have a concept of the absolute of any of these ideas. We have a human definition and all it seems, is that we as a people try to place people closer and closer to that absolute. Yngwie is closer to "THE TECHNICAL GUITARIST" than David Gilmour is. Now, this actually interests me because this entire process is called Essentialism and was originally founded by Plato.
My issue with this way of looking at things is that we have no idea how to really define technical. We have a fuzzy definition, and when one would ask another what their definition of technical was, odds are, you'd get a different answer from person to person. So, what that means to me is that there really is not way to define who is more technical than another; who is more soulful than another. However, this world view really dissolves into "definitional" nihilism. So, what do I do to get out of it? I act in accordance with the modern fuzzy definition. I know that no one can really prove that Yngwie is the more technical guitarist, but you kinda need to go with it, because otherwise, everything you do when comparing two musicians is futile.
Excuse the philosophy rant. I'm kinda on a kick with it.
