Here is my thoughts in a timeline off the top of my head (I might have them out of order)
Kill 'em All - raw, all out in your face rock..good
Master Of.- Great album, their best song in my opinion is on it (Sanitarium)
Ride The...- good album, you can sense a softer side..sorta but still agressive
... And Justice- Blackened has one of the best guitair solos in rock, still a good album, and you can see them going mainstream
Black- great album. able to make hard rock mainstream
---grunge era begins, nobody finds Metallica relavent anymore--
Load- songs written quickly for the era after grunge with one purpose..be played on radio
ReLoad- the garbage that didn't make it onto Load..actually has a sequal to a previous song that was a hit
-They need to make money (b/c they are money hungry) and have no songs era---
Garage INC- since we don't have any songs, lets use other's songs and our brand name
S&M- a greatest hits, sort of, which should have signified their death
-era in which they go from sorta lame to all out lame-
- Some Kind of Monster (Movie)- lets make a movie about how deep we are, and about how much work goes into making a groudbreaking record, this way we can strap our fans for every penny we can.
-Some Kind of Monster- this really needs no explination, but I will becuase I am now on lunchbreak. This forced album wants to show that Metallica still can rock. Between the videos shot at prisons to the songs that are so in your face its laughable, its hard for someone to decifer what is real and whats not, but one thing that is real is this album blows, hard, and often.
