Interestingly, I feel like I've found more "new" music using Spotify's Release Radar playlist instead of their Discover Weekly playlist. I'll typically (and aggressively) mark things as like/don't like in those playlists and add what I like to my own "Testing" playlist to see what sticks to me. Release Radar tends to have more likes than Discover Weekly does, despite what the two are named, and it's providing new artists on top of existing ones I'm already a fan of.

That's usually good enough for me, though the occasional time I'm listening to the radio or a song comes on over the speakers when I'm out and about gets a quick Shazam from me to know what it was.

music zines, friends, going to concerts (opening acts), watching Indy movies (soundtrack). am also interested in ideas from others as I've also seem to have reached the end of spotify's suggestions

https://Last.fm is another service that will track what you listen to and suggest tracks that other people enjoying the same music you do.
It’s basically the same, but it’s 3rd party. I’ve been using that for several years, and it’s given me many great suggestions.

I've been using the 1001 Albums website. It's definitely not foolproof since you won't find anything extremely recent or niche but it forces you to listen to albums you wouldn't normally choose and they are all generally pretty solid (or better). You can also use it in concert (so to speak) with friends so you can listen to the same album on the same day and discuss it together.

It's not a huge number, but I've put 5 albums into rotation just because of this website.

Radio Paradise They have Main, Rock, Mellow and Global streams. Been listening since they started and Global is currently my favourite.

I stalk strangers mostly. I search on rateyourmusic or bandcamp for albums I enjoy, then I check the people that like that album too and what else they like, and I give that a listen.

I've never bothered with the "For You" playlists on Spotify. Always seemed too restrictive.

I just make my own playlists, add a bunch of tracks (at least ~75, but more is ideal), then just start adding the recommended stuff (or using the "Enhance" feature which does that automatically, but apparently that's not an option anymore for some people, though I can still use it for some odd reason).

Also, artists' radio playlists can lead to fun new discoveries.

Although, if I'm being really honest, I've kind of reached a point where I know what I like and don't really feel the need to expand in terms of new genres. It's just about finding new artists, which seem to actually pop up fairly often in my playlists, so I don't have much trouble with that.

Edit: Lol, I feel like this is actually unhelpful because you're talking about expanding your horizons, which I assume means discovering different sounds and genres, whereas I'm just like, "give me more powerful heavy metal lady vocalists, please".

I like to explore the "Selling Right Now" feed and "Discover" tool on Bandcamp, or browse through the "you may also like" on albums I already own. Since I buy almost all of my music there these days anyway it's pretty convenient.

As basic as I sound saying this, it still works: TikTok, local music enthusiastic radio and Anthony Fantano.

I also keep a playlist of albums to check out, so I don't forget.

Spotify's song/artist radio feature as well as looking at recent releases/charts for genres i like or albums i think look interesting on https://rateyourmusic.com/

Mostly just fumbling around with any online service where music is available. Sometimes I'll go to find a piece of music I already like, and see where the suggestions lead me. Othertimes I might read about an artist am into, then try to listen to work by those they list as influences, and who has listed them as influences.

Sometimes I just hear stuff out in the world and come home and try to find it - usually successfully.

Radio free fedi is the best for discovery. All kinds of stuff from all over the fediverse

Radio DJ like Mixcloud and apps, things like Nightwave Plaza for vaporwave/electronica.

last.fm, word of mouth, /r/popheads, and !popheads@poptalk.scrubbles.tech

I spend a lot of time curating from my discover weekly and release radar. But if I really like a band, ill go into the similar bands at the bottom and sometimes I find a few good things there too. A key thing is I aggressively tell Spotify when I don't like something, marking songs or artists as hidden.

What are you into/what do you want to get into?

I own an Alexa. Often, it doesn't understand me 100%, and instead play music based on the bits it could make out.

Gotta love the randomness! As the search is based on keywoards and not rhythm (differently from how I assume Spotify comes up with recommendations), I've discovered neat opera, rock, jazz, electronic, etc.

Although sometimes I really. just. need. to turn on my kitchen!
