@peanut251002 I've listened to a couple of the songs too, though I try to avoid it 'cause I don't want too many spoilers. The songs have a nice Norwegian folk feel to them, though, with fiddle playing and even Sami yoik (yoik is a singing technique used by the indigenious people living in northern Norway, Sweden, Finland and parts of Russia).
Yeah, it's not released in New Zealand until December 26th. I think my older sister may have listened to the songs online, though. She does that kind of thing a lot xD
