Ha! I had never inspired a post before, I'm honored. And I kinda have to comment now, don't I? :P Good thing I actually like your taste in music - it would have been quite funny if you'd gone and posted some Justin Bieber stuff, you know? That would have left me speechless, literally ahah

Anyway, jokes aside, I'd already listened to Jinjer and, of course, Halestorm. The latter is probably my favorite among the songs you've posted, being old-school and all (how did you find a video taken with a smartphone with decent audio? I usually just skip those, maybe because I just hate when people take them instead of listening to the concert ahah) and it's a very powerful piece. I'm listening to a lot of old school stuff lately, although you know, once a metalhead, always a metalhead. Jinjer always left me baffled, in that she can pass from total sweetness and melancholy to a really, really badass growling, she scares me a bit! But there's some sort of emotional release when she starts growling. It reminds me of old Opeth, they had the same effect on me (maybe one of these days I'll post something). I totally love their music, they're really good at what they do.
About the rest, I found In This Moment...interesting. I can see why you like them so much, she's got a way of being fragile and strong at the same time, it's like she's owning everything that makes her who she is and screaming it out.
Diamante, on the other hand, wasn't really my cup of tea. They lacked in grit compared to the other songs, and were a bit more predictable. Her voice was a bit more...plastic? I don't know, I guess I liked the rest much more, to be honest :D

Now to answer your call to action, I'm not gonna post anything superpersonal, but I'm gonna stay on topic with powerful female voices. I've been listening a lot to Sophia Urista lately. It's a bit different from the stuff you posted, more bluesy, but I'm guessing you're gonna like her voice:

Maybe check out her stuff with Brass Against?

Let me know what you think!
