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.Dissection - Storm Of The Light's Bane

4.Sigh - Hangman's Hymn: Musikalische Exequien

5.Vektor - Terminal Redux

2.Sepulcros - Vazio

3.Kassad - Faces Turn Away

4.Dream Theater - Black Clouds & Silver Linings

5.Xanthochroid - Of Erthe And Axen: Act I

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.D.C. Cooper - D.C. Cooper

2.Dali's Dilemma - Manifesto For Futurism

3.Damim - The Difference Engine

4.Dämmerfarben - Im Abendrot

5.Damned Spirits' Dance - Weird Constellations

I always admired people who do really cool lists. But since I don't know anything, I can't really make a good one. So here's the babby-boy of lists, just to get my juices flowing.
Will be updated and expanded upon as I have time and see fit. The goal is to get my top 50 maybe, but there's a long road ahead of that.

1.Neurosis - Souls At Zero

2.A Forest Of Stars - Grave Mounds And Grave Mistakes

3.Neurosis - Times Of Grace

4.Terra Tenebrosa - The Tunnels

5.Amigo The Devil - Everything Is Fine

Simple ranking of all my favorite albums. Favorite song from the album in the notes. Sure to change/expand as I learn and explore more within metal.
2023: This was starting to get too long so I split it into separate lists for albums at each ranking 10 to 7. This list will no longer be updated.

This is a list composed by what I think that is raw oriented black metal, but still only albums with a difference are allowed. Basically Atmospheric, Melodic (Not Symphonic), Experimental stuff. I give some brief explanation of what is so different about those albums. Some bands would deserve the entire discography mentioned, so I opted by putting only one album per band.
Some people tend to think that noise black metal is a very different approach to bm, but it's a well consolidated subgenre. Nothing really experimental or different about it. Same goes for raw oriented dsbm. I'm not gonna spam those subgenres unless something really unique is going on.
Moreover, actually the whole purpose of me making this list is getting more ideas of bands, which should appear on the comments, so start recommending stuff.

1.Ekpyrosis - Mensch Aus Gold

2.The Meads Of Asphodel - Damascus Steel

3.Tjolgtjar - Under Command Of Tjolgtjar

4.Urfaust - Der Freiwillige Bettler

5.Arizmenda - Stillbirth In The Temple Of Venus

These obviously won't ruin your day. Chances are if you are into these styles you'll love this selection. No stylistic borders, but I'm limiting myself to one album per band. These aren't necessarily my favorite albums by these bands, but they are the one's I think fit the best.

10ish years later, I find a lot of my descriptions on these really mediocre. Don't judge my shitty writing.

1.Ævangelist - De Masticatione Mortuorum In Tumulis

2.Abruptum - Potestates Apocalypsis

3.Absolutus - Pugnare In Iis Quae Obtinere Non Possis

4.Abyssal - Novit Enim Dominus Qui Sunt Eius

5.Aderlating - Spear Of Gold And Seraphim Bone Pt. 1
