Sorry Budred but I have to disagree, respectfully of course. The lyrics are pretty harsh/heavy/doom. This is doomier than doom metal and goth combined. It's lou-metal. I like it. And Lars use of the drums is beyond hope: because for him it's Christmas every day :-) Jingle Bells all the way ;-)
The lyrics of another of the songs are posted on Blabbermouth and I have to say they're pretty good. Metallica has earned the right to play with whomever they want. I like the poetry.
