Metallica is my guilty pleasure. I have listened to their discography multiple times now, with the exception of Lucy.
But I really, really like folk metal! My favourite bands so far are: Ensiferum, Wintersun, Týr and Finntroll.
I gotta check out more stuff by Korpiklaani, thanks for mentioning them.
Nekrogoblikon.
Very little of Tool's stuff is metal, I would say, but I like 'em a lot as well.
