I mainly use metal-archives and bandcamp. On metal-archives, I mainly use the similar artists feature, and sometimes search for specific genres from specific countries.

Edit: Oh, and I totally forgot, everynoise.com is also a great resource to get surface level into new genres.

honestly the spotify algorithm is shockingly good at recommending me new music. it knows my taste inside and out. And i listen to almost every genre, but have my specific preferences to every genre. Been on the same account for like 10 years so spotify knows me pretty well by now

Honestly I listen to the radio, but a radio station that’s alternative and aligns with my musical tastes (www.kink.nl, a Dutch station). Stuff I like I look up, and see what’s similar on Spotify or what have been influences to them.

Spotify’s Discover Weekly used to be great for me for a long time and I’d get lots of new music that I liked. it got pretty stale over the past year or so, with stuff that I don’t enjoy at all, and it often recommends me the same songs that I tell it to not recommend. it feels like I’ve reached the end of the internet and there’s no more music left to try.

I usually get a bunch of cool stuff from the Quietus end-of-year list. It’s a lot more varied than the lists of most other publications.

Besides that, mostly Rateyourmusic for sure, especially the “Let’s all find the next gem of [current year]” forum threads. I also used to visit /mu/ for recommendations back in the day, but the culture there made me, uhh, reconsider my life choices.

everynoise.com is pretty great, though it hasn’t kept up with the absolute most recent sub genres lately. Still fantastic, though. Connects with Spotify - which I use.

I’ve discovered more music new to me on Radio Paradise the last few years than anywhere else. They stream up to FLAC quality so an excellent choice for listening on the home stereo. https://radioparadise.com/home

It’s all mostly happenstance and serendipity but I do find a lot of music by googling what I hear in the background of movies and TV. Letterkenny always has really good music and it’s always or almost always by a Canadian group that I might not otherwise encounter.

Now it’s just hopes and prayers

Bandcamp daily Blogs Since I listen mostly to hip hop and rappers collaborate often, features is a big part of the way I discover new music

I find the Tidal algorithm to be excellent. Beyond that I think a good trick is checking out different services. Playing the same artist or song radio on Spotify will be a very different experience to Pandora or YouTube Music or again Tidal. That and a few of them actually have a ‘discovery’, or whatever they call it, setting on the radio that will specifically recommend things that are new and/or unexpected.

I use a combination of Spotify discover weekly playlists, related artist lists, and lately I’ve been finding a random new category that Spotify curates and then searching for playlists of the same type that are curated by users. I think I get more deep cuts that way.

Certainly skews towards specific tastes and genres [indie, punk, diy, and sometimes undergroud hip-hop], but super active and on top of new music and related info

I follow the news portion as well, but for pure new music discovery: https://www.brooklynvegan.com/tags/new-songs/?from=trending

last.fm has awesome algorithms.

Musicmap.com lets you search for an artist, then graphically displays similar artists around them. Great way to find new artists similar to old ones you know you like.
