It was a manual process for me personally, finding them through message boards and forums (I know that's not much help). I'd also use https://www.music-map.com. /r/listentothis on reddit is also a good source of tracks.

What I mainly do now is look for Spotify playlists by record labels that represent artists I like, or look for playlists made by artists I listen to.

Shout out to holyfuckingshit40000 on blogspot, it's long gone now. But that was my favourite music blog, to the point I wanted to meet the person who ran it and buy them a drink or something, because almost everything they recommended I loved. Just now I've found that someone compiled a list of the recommendations, check it out: https://joseph.pallamidessi.fr/2020/05/03/holyfuckingshit400... (it's missing some from memory, but it's a diverse collection of some good music).

A few months ago, I started listening to new-music programs on BBC Music Introducing [1], particularly the London program [2]. As you might guess from how I spell “programs,” I’m not British and have never lived in the U.K. But I’m an older guy who responds most viscerally to the same old songs I liked as a teenager. Listening to music created by young people today helps to get me out of that rut.

I still like https://hypem.com as a meta music site aggregator. Also https://www.indieshuffle.com/

Sasha Frere-Jones used to be the music critic at the New Yorker and writes a fantastic (although somewhat irregular) substack blog > https://substack.sashafrerejones.com/

I frequent the bandcamp daily blog, and I follow a few people on bandcamp who tend to actively buy music I’m interested in (I just go through the users who have bought an album I like, then I look at their other purchases). On top of that bandcamp sends me a weekly “you may be interested in” email that often has at least one thing I’m actually interested in.

I read some blogs. But overall I discover a lot on bandcamp - more than I can process.

I've been enjoying the "All Songs Considered" podcast from NPR. Discovered a lot of great music through them.
