I think i don't post enough about women in metal so here's a list of top 10 Symphonic Metal FEMALE Singers by my opinion. Enjoy!
1 Simone Simons (Epica)
2 Tarja Turunen (Nightwish)
3 Lisa Middelhauve (Xandria)
4 Anna "Aya" Stefanowicz (UnSun)
5 Monika Pedersen (Sirenia)
6 Cristina Scabbia (Lacuna Coil)
7 Amy Lee (Evanescence)
8 Sharon den Adel (Within Temptation)
9 Charlotte Wessels (Delain)
10 Elize Ryd (Amaranthe)
I know not every single pick is Symphonic some are gothic or heavy but still amazing vocals!
