I generally do this for all my media, but I will never do this for music, there's just such a huge lack of discoverability. Are you just never seeking out new music on the fly?
Oh, you like Cattle Decapitation? Then you might like Skinless, Guttural Secrete, Devourment, Pig Destroyer, Rivers of Nihil...
It's not good with really new artists (e.g., The Anchoret, Temic), and artists that have had significant shifts over their careers might give you overly broad results. But it gives you some starting points.
Personally I use a combination of a large library of mp3s plus I listen to SiriusXM in the car to discover new artists. I also like to go through the backlogs of artists I find I like, and also dig into their earlier/later works
This brings me to an interesting phenomenom with me, I tend to dislike contemporary music, but about 10 years later or so I wtart to really enjoy it.
Then I start listening to music on YT, start playing the same song over and over, and start checking out other songs by the artist, and create a playlist on yt where I can listen to those songs over and over, then I start getting ready to buy the songs on iTunes.
Right now, the latest songs I bought on iTunes was from the Red Alert soundtrack from Frank Klepacki, Blue by Eiffel 65, Walk On Water by Milk Inc, two songs from SkyMarshall Arts, a few songs from the Shock Treatment soundtrack, some Scooter songs, and a song from Gina G.
I go through phases where I listen to a particular genere/artist constantly and will then buy a few songs here and there that interest me, in 2022 I was dealing with double flat feet, double heel spurs, a bad knee and more crap, I would drag myself home from the busstop crying from the pain that each step caused, and I just blasted Sabaton constantly, I got energy and was able to keep working both in the office and on getting better.
And when I got better, I started listening to more Eurodance and fun music, so I bought plenty of Dr. Bombay and Dr. Macdoo, and as I bought my first car this summer I got into classical music set to a disco beat and bought Hooked on classics 1, 2 and 3 as well as Hooked on Themes.
So while I don't constantly look for new music, I am not shy of buying it when I find it.
