They're not the typical stars we all used to know before,I really wanted to add some of very underrated but somewhat impressive vocalists. Any suggestion is welcomed,so let me know if you really know more.This is my first attempt of making a list, erm salute to these awesome ladies.
Some of them are really inspirational.
Edit: I don't really want to mention every female passing by the metal neighborhood
EDIT 2: I changed the title and criteria, as the list is getting longer I avoid using any exact digit in the title, this list may exceed that digit anyway.So no more restrictions to any of them.
