@kaki068 Metallica's early stuff is great, but not so much since the Black album IMO. The music that I've been listening to for the last 30 or so years blows anything they've ever done out of the water. Here's a short list of bands that I listen to to get me through the days if you're interested.
BEHEMOTH, INQUISITION, WATAIN, PATRIARKH, AKHLYS, BELPHEGOR, GRIMA, EMPEROR, IMMORTAL, and MARDUK.
Happy listening.
