Halestorm. Lizzy Hale has a great voice. Paramore. I love them and Hayley Williams is awesome. Lacuna Coil. I think they call their genre Love Metal. I like it. Nightwish. But only when Tarja was there. She's my favorite female vocalist and no one can replace her. Evanscence. Amy Lee is great. Joan Jett & The Blackhearts. No explanation needed. Classic.
