What do you think about the melodic death metal genre?

1. That's just your opinion. I think that if you compare their technique and so on, Maiden would give almost anyone a run for their money. But I won't argue about tastes, as that's already been discussed extensively.
2. In my opinion, it's not necessary to combine many styles; it's enough to simply perform your own style well. And if many styles are combined, then most likely a new style will be born, as happened with Finnish mdm.
3. Perhaps I shouldn't even argue with such a music expert as you, or you might make me look like a fool and embarrass me in front of everyone. That's scary.
