I find myself every year that I find less music that I like. I use a mixed method to find albums and artists. I follow various groups on social media networks (vk), read music magazines and use youtubes recommendations to pick up new stuff.
What are your tools to find new music?
If I find the music is nice, I will try to find the music title in video description or comment. "Helpless" by Federico Martelli [0] and "Time" by Arca [1] are the examples that I love.
For specific/niche things, certain subreddits get a fair amount of posts. I suggest reverse searching links to music you enjoy instead of trying to look up a particular sub.
Hype machine and soundcloud also help a bit.
Spotify - Start with an artist I like, listen to all the similar suggested artists, recursively do this until I'm back to the original artist.
YouTube - same as above except with channels. Lately I've been into stoner doom metal, so 666MrDoom is the starting point. From there I listen to all the related channels.
It's a lot of manual labor but I enjoy the process and often stumble upon gems that make my skin tingle.
Human curation is ideal, as nothing is worse than being holed into an algorithmic artistic filter bubble. Art should knock you sideways, not confirm your tastes.
2) I search youtube for "tiny desk contest"
3) Tildes has a new music group which is quite good.
4) I sub to YT channels that play sessions. EG Western AF, Gems on VHS, Little Orange Room Sessions.
5) I used to use Usenet (alt.binaries.sounds.1940s.mp, (and 50s, 60s, 70s, 80s, and world-music) but it's a bit frustrating to use now.
