I became a fan in 2000-2001, so I was able to appreciate their discography without the social context in which the albums were released. I discovered their music alll at once without any particular order, so I became huge fan of Enter Sandman, Fade to Black, Unforgiven, Sad but true, Master of Puppets, The thing that Should not be, Fuel, Until it Sleeps and Whiskey in the Jar and some others, all at the same time.
So, for me, I don't have any particular issue with any of their albums. Of course, now after many many years, I like some albums more than others, my favorite are
1. AJFA
2. RTL
3. MOP / TBA
4. Load
Regarding TBA, since many years ago, I cannot listen to Enter Sandman, Sad but True, Nothing else matters on my own. But the rest of the album is great IMO, specially Don't tread on me, Struggle within, God that failed, My friend of misery & Through the never.
