im more a hardcore/metal oriented person so i would say some good bands fronting women would be
-walls of jericho
-arch enemy
-in this moment

Flyleaf of course
Hailstorm
Im not going to try to pretend like its metal but Monsters- Meg & Dia is pretty good
Lacuna Coil

Arch Enemy. Angela Gossow is from Germany and anyone who says Otep has the most brutal female vocals has never turned their radio off. Angela can growl better than most men can

Estrum is a really good metal band with an amazing singer. No growling, just good singing.

YouTube - Estrum - Abiosis

Let me know if you like them...

Within Temptation is a great band yes, others being Epica, Tristania, Nightwish, After Forever, Leaves' Eyes, The Gathering, Theatre of Tragedy, Tapping the Vein, Lacuna Coil, Evanescence [old, before Fallen], Birthday Massacre, Porcelain and the Tramps [absolutely amazing band].

Otep, Arch Enemy, there are loads!

My favorites are Fleetwood Mac and Heart.

umn there is a band, Holy Moses, from Germany. The vocalist is a she, and she really kick ass, she have the style of Angela Gossow, I'm not saying shes better than Angela, in fact I don't think anyone is, but shes just good.
Try listening to something from Holy Moses, anything will do just right...
