I'll see you your boss music, and raise you more fitting music. Not to say your music isn't good, it's just...look at the title, man!
You like Nightwish, too? Nice! Although I got to them, as well as other great metal bands, by looking what Van Canto had done covers of
I really like the original work, so I had to love this: Also, I reallylike both of these: Yes, mostly A Capella metal is kind of strange at first, but the people at Van Canto do it really great! This is my absolute favourite by them, because of the goosebumps it always gives me

Van Canto are pretty awesome. Although... I don't think much of the woman. I don't know why but to me she doesn't really... fit.
