Good ranking! I think personally, I slightly prefer Stand Up and Fight to Battle Metal, but those two are definitely the closest together - The Varangian Way is for sure the absolute champion and Turisas2013 sadly languishing at the bottom of the pile, although I still like some of those tracks a fair bit.
The way you berated Turisas 2013 was actually a successful way to advertise it to me. I'm currently listening to it and also am finding it quite fun. Thank you!
Don't think the lai lai lai lai singing is exclusively Finnish as Arkona of Russia does that too. Possibly a slavic influence as Finland was a Russian territory for a time.
