Melody in Mikey's growls?

My point of view would be that the discussion is irrelevant, because growled vocals derive their melody from the guitars under - they become one. This is my argument every time people claim there is no melody in growled vocals. When you listen to good music, you shouldn't listen to any single instrument really. You still hear the words, it's just that the guitar decorates them, like they are yet not complete the way they come out of the singer's mouth. Who would listen to growling with nothing beneath it?

Of course this leads to the Opeth phenomenon: when the singer lets the instruments worry about melody, concentrating on pure growling, he can sometimes reach levels of emotion and power not possible by singing clean. ;)
