Look at it this way...
Kill 'em All = classic
Ride the Lightning = classic
Master of Puppets = classic
After these three albums, they got a taste of being popular, they appeased to people by putting out ...And Justice for All. Which really is not a good album. The Black Album was purely appealing to what people wanted to hear. Listen to it, there is nothing new, nothing showing them experimenting or playing real music. After the Black Album? Can anyone honestly say that they like Load, Re-Load, St. Anger, or Death Magnetic musically, or lyrically? Anyway, I don't want to start a flame war, so I will redirect the thread back to it's topic of do people like the set-list of World Tour.
