I was today days old when I found a website that maps every music genre Spotify has ever catalogued — thousands of them, from pop to musica alagoana — as a giant scatter-plot you can click on to hear a 30-second sample. It's called Every Noise at Once. The scan button is where it gets dangerous.
Every Noise at Once was built by Glenn McDonald, who spent years as Spotify's data and genre engineer. His job was to figure out what kind of music was what, algorithmically, at scale. Every Noise at Once is what that looked like from the inside: a visual map of where every genre lives in relation to every other genre, organized along two axes. Top of the map is mechanistic — tight rhythms, electronic production. Bottom is organic — acoustic instruments, variable human timing. Left is atmospheric and ambient. Right is loud and dense. Genres cluster near their neighbors. bedroom pop sits near lo-fi indie. cumbia is nowhere near kawaii future bass. You can get genuinely lost.
How it works
The main page is a scatter-plot. Every label is a genre. Hover over one and click the small play button — you get a 30-second representative sample for that genre. Click the label itself and you get a genre page: a map of artists within that genre, each one hoverable and playable. The map has roughly 6,000 genres. There is no end to it.
The scan feature (this is the one)
On any genre page, there's a scan button. Click it and the site rapidly plays short audio snippets from that genre, one artist at a time, in sequence — a machine-gun sample of what that genre actually sounds like across its breadth. Five seconds of one artist. Five seconds of the next. You can scan through deep jazz fusion or afrobeats or nintendocore in about 60 seconds and know definitively whether it's for you. This is the fastest music discovery loop that has ever existed. It's better than any algorithm, because you're in control of the speed and direction.
The scan feature also works for artist discovery inside a genre. If you want to find every Spotify artist who makes vapor twitch or brazilian gospel or chicago blues, the genre page lists them all, hoverable for samples, scannable in sequence. You can find your new favorite artist in three minutes of scanning a microgenre you've never heard of.
A few things worth knowing
- Glenn McDonald was laid off from Spotify in late 2023. The site is no longer being updated with new genre data. But the snapshot it captured is enormous and the site still works perfectly — the backlog of genres is a lifetime of listening.
- The vertical axis is organic vs. mechanistic. Top of the map = electronic, tight, programmed. Bottom = acoustic, human-paced, expressive. The layout is not arbitrary.
- You can look up any artist. The search box in the top-left finds any artist on Spotify and shows you which genre(s) they're filed under and which other artists are nearby on the map.
- There's a Spotify playlist for every genre. On each genre page, a link opens a Spotify playlist of representative tracks. No account needed to browse the map. Spotify account needed to play the playlists.
- It's completely free. No account, no login, no ads. Just the map.
Every Noise at Once is one of those sites that makes you realize how weird and massive and specific music has gotten in the streaming era. There are genres on this map that have hundreds of artists and millions of listeners and you have never heard of them. The scan button is how you fix that. Go to everynoise.com and pick a genre you've never heard of. Scan it for 60 seconds. Something will catch.
