Do you like heavy metal?  Metallica is my favorite heavy metal band.
I grew up in the 1980's so I heard a lot of heavy metal growing up!  
It's crazy how they attracted such a wide audience while being derided by critics.
I guess it was like any generation's "rebel" music, like Elvis was criticized in his day, punk got criticized too. 
What really drew me to Metallica was the band's fast tempo's and instrumentals.
Do you have a favorite Metallica album or song?
...And Justice for All (album)
...And Justice for All is the fourth studio album by American heavy metal band Metallica, released on August 25, 1988, through Elektra Records. It is the first Metallica studio album to feature bassist Jason Newsted after the death of Cliff Burton in 1986.
Four months of recording ensued in early 1988 at One on One Recording Studios in Los Angeles. The aggressive complexity, fast tempos, and few verse-chorus structures are complemented by an infamously dry and sterile final mix
being certified Silver in the United Kingdom.
In 2015, Korn vocalist Jonathan Davis stated "My favorite Faith No More record is "The Real Thing". That's when Mike Patton took over. That's the one. [Although] I do like "We Care a Lot". We got a lot of our influences from "The Real Thing". It showed everybody you could do heavy music and not be "metal". It was something completely different."
Legacy.
