See I'd vote on this (aside from only knowing Evanescence and Paramore in this I have other reasons to abstain) but you forgot some fantastic female names in rock such as;

Cristina Scabbia - Lacuna Coil

Brody Dalle - Distillers

Kittie (all female band)

Courtney Love (love her or hate her she's still successful)

The Sahara Hotnights (I'll just list the entire band here since they're all female)

So many others out there this is just the ones I remember of the top of my head here.
