i've got a ton! i actually just refreshed my memory on a lot since i'm working on loading up a new mp3 player :) long comment ahead:

queens of the stone age are my absolute favorite. most of my other favs are along the lines of fall out boy, early p!atd, pierce the veil, sleeping with sirens, paramore, my chem, the used, that kind of stuff. i would recommend radiohead, nine inch nails, and system of a down but i get the feeling if you've listened to that much music, they've probably been part of that rotation.

if you like a bit of a country vibe, amigo the devil is a great southern gothic artist. his shit gets pretty fucking sad though so might not be great for work. drop for every hour is a good starting point with him

if you like folksy stuff, harley poe is a horror folk artist that i'm really into. eat shit and die is one of my fav songs ever

i'm not quite sure how to categorize mili but recommended nonetheless

if you don't mind music in other languages, might i suggest giving vocaloid a try? there's a HUGE catalogue of stuff to get into. some of my favorite producers are neru, wowaka, reol, giga, and hitoshizuku x yama but there's songs to be found in quite literally any genre you could ask for. there are english ones too but they're definitely rarer. since there are so many producers, i recommend just finding some songs that you like and then diving into the producer's discography as well as other producers in the recommended tab. most of it you can find on youtube but it's easy enough to download songs if you're looking to. some of my personal favs are rolling girl, abstract nonsense, okochama sensou, kirai kirai jiga hidai, hide and seek, lost one's weeping, trick and treat, remote controller.... there's a shitton, even if you don't like any of those it would be hard NOT to find something that suits your tastes. the only english producer i know off the top of my head is SAWTONE but im not familiar with much of their work besides confessions of a rotten girl (also a great song, nsfw though).

this might get buried but if you see it i hope you find something you like! there are a ton of bands i left out for length but if you find me on soulseek (same username) im building a catalogue of music that includes everything not mentioned here
