Listening through Bathory's entire output in chronological order and I once again realize that I only enjoy the viking styled songs apart from a handful of songs from The Return and Under The Sign of the Black Mark. The rest is pretty much garbage.
The thrash songs on Blood Fire Death are blatantly trying to compete with and copying what Slayer did 2-3 years before that. Even "The Return" smells of copycat bullshit.
Let's not even start with the abominations that are Requiem and Octagon. Failed attempts at keeping up with the times.
Hammerheart, Twilight of the Gods, Blood on Ice, Nordland 1+2, The title track and opener of Destroyer of Worlds, The top 3 tracks on UTSOTBM + the 3 viking songs on BFD are all the Bathory I will ever need.
