Hahah dam eh. Yah if you listen to a song a lot you will stop liking it.
Nightwish is cool. Im pretty sure that chick left the band. And everyone bitches about the new singer lol.
In terms of female singers in metal, this one my fav. Sounds more raspy to suit rock better.

Doro Pessh and the chick from Phantom Blue are really good too.
