I have finally caved in and made a top 200 list. The main focus here is metal, so no Rush, no King Crimson, Deep Purple, or GY!BE are in the list, but I do still love those bands and others that could have qualified.
The list mostly contains albums, but some EPs, demos, splits, and compilations are also featured every now and then. I also tried to avoid including demos or EPs that were too short but there’s still a few of them.
Enjoy!

1.Dream Theater - Metropolis Pt. 2: Scenes From A Memory

2.Windir - Arntor

3.Vektor - Terminal Redux

4.Dissection - Storm Of The Light's Bane

5.Sigh - Hangman's Hymn: Musikalische Exequien

Here it is, the third list of albums that could be a hidden gem. You can check the first list and the second.
This third list will have albums of invisible bands with 15 to 35 votes and with a green rating (8.5 and up).
Let's listen some music.

1.Bad Company - Bad Company

2.Tony MacAlpine - Edge Of Insanity

3.Tony MacAlpine - Maximum Security

4.D-A-D - No Fuel Left For The Pilgrims

5.Skinny Puppy - Rabies

This list is meant to be an extensive, but by no means exhaustive, collection of the greatest (modern) metal albums and eps. Running the gamut from avant-garde to trve norweigan black metal. *As someone who is young in age, my tastes tend to revolve around the period of the 80s to the present.* Although certain metal albums from before will certainly be featured, the period of the 60s-70s will be under-represented. I refer you to this excellent list to gain a better appreciation for some of the best metal from that period: https://rateyourmusic.com/list/freis/martin_popoffs_the_top_500_heavy_metal_albums_of_all_time/

1.S.V.E.S.T. - Veritas Diaboli Manet In Aeternum: Le Diable Est Ma Raison

2.Sabachthani - Miserable Endings

3.Sabaoth - Les Illuminations

4.Sabaton - Carolus Rex

5.Sabbat - Dreamweaver

Here's a little list displaying my personal favorite death metal albums, based on the same idea as my heavy metal list, thus stressing the raw and the genuine. For me death metal has to be crushing, then coloured with atmosphere. Some of my choices may seem exotic, considering the list overall, but it's what broadens it. Rules : one album per band, the order isn't strict (still bottom albums are weaker than their predecessors). Many good tbdm bands are lacking, mostly because of their unfitting sound. If you think some kick-ass piece are missing, don't hesitate to suggest them. Enjoy.

1.Carcass - Necroticism: Descanting The Insalubrious

2.Suffocation - Pierced From Within

3.Cynic - Focus

4.Septicflesh - Εσοπτρον

5.Death - Symbolic

      View entire list ››

Rules:
1. One album per band
2. Alphabetic order
3. Only albums with less than 30 votes + albums not available on MS
