Maybe I'm just a nostalgic old fuddy-duddy, but I say personal music recommendations are better than algorithms. I used to get music recommendations exclusively from humans (ie friends and blogs), and I think they're more likely to expose you to stuff you wouldn't otherwise listen to. Open your horizons a bit.
Not sure what happened to my friends. And I guess blogs are still a thing, but who has time to read things from other humans when you can just press play on "My new music mix" on Apple Music or whatever?
Here are three sources I consistently use to find new music from a wide range of sources that are still maintained by humans.
"Song of the day" podcasts
These are podcasts that post a new song every day. No talk, just an mp3. Super easy way to give new music a chance.
Hype Machine Stacks
Hype Machine started out as a way to see what independent music blogs were posting the most. It still does that, I guess. But they also have "stacks" which are curated mixes. They're really good! Check it out.
All Songs Considered podcast
I call this the music nerd podcast. It's produced by NPR. There are a bunch of standing hosts plus a bunch of rotating folks they talk to. It's good. Listen here.
