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

One album per artist in alphabetical order which happen to be my favorites. Feels like an addendum to the ?Beginner's Guide To Building A Prog Collection" (http://www.metalstorm.net/users/list.php?list_id=58) often mentioning the same band but different releases.

1.36 Crazyfists - A Snow Capped Romance

2.Agrypnie - 16[485]

3.Ahab - The Call Of The Wretched Sea

4.Akercocke - Words That Go Unspoken, Deeds That Go Undone

5.Alkaloid - Liquid Anatomy

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 list contains most beautiful, majestic and soul-touching releases I've ever experienced.

Albums are ranked by the year,I think this way is more useful.

I will keep expanding my list as i can.

2.Blut Aus Nord - Ultima Thulée

3.Deinonychus - The Silence Of December

4.Blut Aus Nord - Memoria Vetusta I - Fathers Of The Icy Age

This is a favorites list, not a guide or anything of that sort. It just highlights the albums that I've enjoyed listening to and spinned extensively since last November (When I got into this monolithic genre.) One entry for each band. The descriptions aren't necessarily descriptions of the music. I just wrote what came to my mind. I will update with new albums frequently.
EDIT: Got to 50 entries, so I guess I'll stop for now. I want more time to revisit these 50, get into the other albums of the bands listed below and delve into other genres of metal. I guess that taking a break from black metal (at least new stuff) will ensure that I won't get bored of it. It is likely that I'll continue this list by the half of July.

1.A Forest Of Stars - Opportunistic Thieves Of Spring

2.Addaura - Burning For The Ancient

3.Agalloch - Pale Folklore

4.Alcest - Écailles De Lune

5.Alda - : Tahoma :
