Need some good recommendations for music in general

Hey nerds, riffing off this thread I also want to start adding music to my campaign. I was wondering if any of you knew of some cornucopia of music searchable by ... feeling? Currently I just try to find synonyms for the feel I'm looking for, and honestly, like all of you, I'm lazy and I don't want to spend so much time looking for the "right kind" of music for every kind of situation.

P.S. I realize this sounds stupid. That's because I'm lying, my true motivation is to learn how to use this tool to compose original motifs for recurring themes, places and characters. I know nothing about music theory and can't play any instruments, so forgive my reluctance to admit this arrogant quest of hubris. I promise to report my findings either way, but for now, I want to be able to find a lot of different pieces around some theme and steal ideas from all of them.

Edit: Just so you guys don't think I'm crazy for thinking a talentless shleb like myself can write music, here's what I managed to throw together and polish over the course of an hour: https://www.hooktheory.com/hookpad/view/uMS1hszzc7Ui
It's 6 increasingly complex versions of the same theme. It's supposed to be the background for a village that just lost 1/5 of its population to a raid, like, 12 hours ago.
Speed it up to 240 bpm if you don't have the patience to listen to it at funeral speed.
And for some reason it won't let me share it with non-default instruments, so just take my word for it - violins playing the harmony emphasize the sadishness.
