Ride the Lightning. Easy one for me since I don't like almost every other song on that list.
Weird, I always thought Ride the Lightning was released in '82. I heard it the year it came out then but didn't really start liking it until after I saw them live in 89. I mean, I always liked Fade to Black and a few other tunes but they struck me as kind of predictable and I was getting into a lot of 60s and 70s stuff I had ignored when I first heard them.
