What is the Best Rock Band Fronted by a Female? [POLL]

With this week's Question of the Week, I asked you what are the best bands fronted by a female.  Based off of your answers on my Facebook page, I've created a poll for us to vote on the best rock band fronted by a female. There are a ton of bands in the history of rock that have been fronted by women, who have kicked ass.  From Pat Benatar and Lita Ford, to Halestorm and Evanescence, you guys had some great answers.

Now it's time to vote!

Just simply vote for what you think is the best rock band fronted by a female.
