I'm not the biggest Metallica head out there, but I just chuck them in the good pile of heavy vinyl, along with the likes of D.R.I., Faith No More, Helmet, King Diamond, Death, Sabbath, Pentagram, Type O Negative... some of the basics.
I can't get enough Ghost, lately.
To me, Metallica was good and I'll remember what it was during those times and continue to enjoy it, without mucking it up beyond the '80's.
