It took some time, but - I was able to gather my personal favorites with links. Enjoy!
Hanged King:
I organased these ones on a scale from "songs about an eldrich nightmare god" to "songs about a bad or/and struggling man, turning into an eldrich nightmare god".
P.S. On the second listening - it turned out that in this order it a plot about a god recalling and mourning its mortal past - so maybe the Hanged King's name is truly hanted and infects all that it touches with a narrative, damn.
Black Sabbath - Master Of Insanity (under the mask, there will be - the Master of Insanityyyyyyyyyyeaaaaa)
arai tasuku - Lizzy's delights (TW: VERY loud)
arai tasuku - Twisted Apple trees
arai tasuku - Nightmare circus feat. Itaru Baba
arai tasuku - Fuck off Aliceeeeeee feat. Itaru Baba
Jim Yosef - King of Hearts (ft. Scarlett)
Dirt Poor Robins - Babylon
Mother Mother - Burning Pile
Lemon Demon - When He Died
The Ambassador of Alagadda:
Mix of cunty and existentialy nightmarish songs about being nothing, being haunted, being haunted but you kinda deserve it, and being at the top of the world at a too high cost. You can add "Dear Alice" pair of songs from the Hanged King playlist if you feel like it.
Anya Nami - Old Doll (voice cover)
Dead Man's Bones - In The Room Where You Sleep
arai tasuku - C is for Colleen who wasted away
Kikuo - Waltz of Malice (this caver is in my favorites)
Master Mirror - Ashley Serena
Raichel Rose Mitchell - Carnaval
Baby Bugs - Autotheist (TW: Religious trauma)
Jamine Paige - ROT FOR CLOUT (feat. Kasane Teto)
Black Lord, Nigredo:
Rot, manipulation and distruction. Songs strait from beneagh the dark rock soil, where the evil was supposed to be forever forgotten. The lord that lost its flesh and regals - and yet, it is free, and it never was happier.
Will Wood and the Tapeworms - Hand Me My Shovel, I'm Going in!
Mother Mother - Wrecking Ball
The Circus Contraption Band - If I Told You Once (TW: graphic description of suicide, handging, and possibly implied necrophilia)
The Blake Robinson Synthetic Orchestra - Little Birds ft. Gloom Darkheart
The Blake Robinson Synthetic Orchestra - Marionette
BLVCK CEILING - davey drawings
Nero's Day at Disneyland - Mascara Running Everywhere
Psychic Rites - Killer (TW: A mummified corpse on a thumbnail)
White Lord, Albedo:
Mostly wizardy and cold music, sometimes with words, or some ortodox chirch motifs. Make you think about alchemy or horrific magical manipulations. They feel like a louring sea.
ΔXIUS LIИK & ножевые ранения – NНΞЙ
Ведьмина Поляна & ножевые ранения – Ведьма
Dr. Rader – Save Yourself
Boards of Canada - Music Is Math
Crystal Castles - Violent Dreams (Sidewalks and Skeletons REMIX)
NEDOSTUPNOSTЬ - NEDOSTUPNOSTЬ III
polnalyubvi - Девочка и Море (TW: suicide)
Maybe all lords are the union of opposites, as all opposites are having a grain of their counterpart inside. Diligence can be apathetic and so, deciduous. Mirth can be forced into despair, and Anguish can result in triumph. And so, Hatred can mask as love, and love be worse than hatred. If the SCP-6224 told us anything, that is there no one in Alagadda who would be more passionate about its projects, than the Great Maestro, the Bearer of the Mask of Hatred.
Jyc Row - Aqasha, Goddess of Destruction (feat. Shelley Harland)
Sagan Hawkes - What Lies Within It (Basilisk 2000 is a very Citrinitas&Albedo themed project, check it out)
Åpostol – λucifer's hatred
SLAMER - ฿ΣΣŽ Ī№ ★ ŦĦΣ ₮ƦÅǷ (TW: trypophobia)
††† (Crosses) - Bitches Brew [Sidewalks and Skeletons REMIX]
Steampianist - Wag Kang Bibitaw - Feat. Gumi
arai tasuku - Been a While feat. coma
Red Lord, Rubedo:
Lots of blood, lots of fun, if someone getting a kick out of its situation - it's Rubedo, the pinicle of self-actualisation and hedonizm. It can feel love, and sympathy, and even regret - almost no Alagaddian has this emotion. But, it chooses not to. You can't make a whine vithout some blood, so sorry, but you go into a comically oversized meat grinder. Enjoy!
Jerma Remix: THE MEAT GRINDER
The Blake Robinson Synthetic Orchestra - One by One ft. Gloom Darkheart
Madds Buckley - The Red Means I Love You
Kikuo - Red ridinghood's Wolf
Avenged Sevenfold - A Little Piece Of Heaven (TW: Necrophilia, Comically Graphic Murder, lots of swearing)
Tally Hall - Turn The Lights Off
If you want some allagadish semi-classical music, check out Saint Preux - he's AWESOME.
And arai tasuku & Mili - Holy and Darkness is a long one and sounds like Alagadda, meshed up together pieses of dream over someone long forgotten and lost trying to talk to you, so you not end up like they did.
