You sure its not just another vocal layer of Mathias?
I'm also not a huge fan of the female's voice. I do like her in the chorus of Dreams and Pyres, so maybe its just certain octaves I don't like.
Also, as much as I love Dreams and Pyres, I cannot stand where she says "of demons and hell's fire" it's so corny and makes me cringe every time. Anyone else feel weird when she sings that line?
Amazing album though.
