Your quite right, I don't particularily like typical death metal vocals (no i don't think death metal is shit, it's usually quite technically profficient and if i ignore the vocals, alot of it is quite good.) but I don't think they should be "overly prominently" in black metal. Oh by the way my band uses death metal vocals on occasion and I think it adds a lot of variety, its just not used all the time, I just think, when it comes to the most recent album, Galders vocals in particular suck and if they were used in Dimmu then that would be really shitty.
