It's been one of my favourite bands for half a decade now. I've got all their albums - save for the Over the Hills and Far Away EP - and still enjoy listening to them on a regular basis. I'm gonna see them live next month, which is awesome. Unfortunately I'll have to to do that alone since not only did I plan to go there with my ex girlfriend when we were still together, it's sold out as well. Oh well, Nightwish won't be any less kickass because of that.
Anyway >_> it's awesome music and once you've gotten used to Anette's voice, which isn't all that bad, you'll grow fond of Dark Passion Play as well.
