and Tarja and Amy and SHARON

Anette, Tarja, and Elize too. But Sharon will always be my favorite singer. Her voice is just so beautiful and powerful and like a choir of angels.

Ellie Goulding. LOL

You forgot Floor Jansen, current vocalist of Nightwish.

I also like Sharon. The rest are meh to me. I love Evanescence but I think Amy as a vocalist is a bit overrated, especially when she's constantly being compared to Symphonic Metal frontwomen who've had classical vocal training. Sarah Brightman is incredibly talented but I don't like her sickly sweet voice when she doesn't sing opera, which really puts me off.

If this were based on talent alone, Sarah and Tarja would cream everyone else because opera or operatic singing like Tarja does is one of the hardest styles of singing to do, much harder than ordinary rock vocals. /opinionated, ignore me if you want.

^Oh, I didn't know they change the vocalist again...

^It's okay, so far they only have a live album with her, she's really recent. ;)
