I would also have to say that the top four albums are pretty much tied for first, and are vastly superior to the next two. I've heard better by the same band. I didn't really like about half of the album, but some of the songs are pretty good. My personal favorite is Devil's Dance. The Unforgiven II can learn something from The Unforgiven.
Fuel is pretty cool.
I guess Hero of the Day and King Nothing are the two songs I like most. I think this is generally acknowledged as MetallicA's low point. I went to their concert this summer in Giants Stadium. We sat thirteen rows from the stage. A truly great experience, if you don't value your ears.
