Anthropic launched Claude FM on May 5, 2026. A 24/7 stream with the tagline music for thinking and building. The dev crowd took to it fast. People in the chat are posting things like "I shipped more in three hours of this than in the past week."

Roam FM was built around the same idea: when you're trying to think, the wrong sound breaks you, and the right sound disappears. Claude FM is a good source for that. It's also a single source. One playlist, one curator. If that's what you need, stop reading and go listen.

This post is for the other hours. The ones when the same loop starts narrating your bug. When you want a different city in your headphones.

The case for real radio

Claude FM is curated. Roam FM is the opposite. It pulls from over 40,000 real radio stations in more than 200 countries, broadcasting right now to whoever is in range of their tower. A jazz station in Tokyo. A community radio in Reykjavik. A Brazilian baile funk channel in São Paulo. A French talk show that has been running since 1982.

Real radio has weather forecasts. Local ads. A DJ saying something you can't quite make out. None of it was made for focus, which is part of why it works for focus. Your brain gives up on parsing and lets the sound become atmosphere.

Voices in a language you don't speak

You can absolutely focus while voices are talking, as long as you don't understand them.

English talk radio kills my concentration. Japanese talk radio is a balm. The voices have rhythm, the inflection has feeling, but I can't latch onto meaning, so I stop trying. The sound becomes warm white noise, more alive than rain on a roof.

Music does this too, but voices add a human quality that's hard to fake. Late night DJs you can't follow. Cooking shows in Korean. Sports commentary in Portuguese. Half the time I'm not listening to music at all, I'm listening to people talk in languages I don't know.

Filtering by language

Language ended up as one of the central controls in Roam FM.

You can filter to a specific language. Want Japanese for an afternoon? Set the filter to Japanese, and that's all you get. Same for English, Spanish, Mandarin, anything else. It's a quick way to put yourself in a city without leaving your desk.

By default, Roam FM filters out your own native language. Stations you can understand will pull you out of focus, and that's rarely what you want during work. You can turn the default off whenever you want.

A few setups that work, depending on what you're doing:

• Writing code: pick one language you don't speak. Japanese lo-fi or Brazilian late night radio are good starting points.
• Writing prose: drop voices entirely, filter to ambient or lo-fi tags.
• Reading or thinking: try a language with very different phonology from yours. Vietnamese, Finnish, Yoruba. The unfamiliarity is the feature.
• Long sessions: rotate cities every hour or two.

Menu bar, not browser tab

Roam FM lives in your menu bar. Nothing to close by accident, just a small icon at the top of your screen playing something from somewhere.

The keyboard shortcut for "skip to a random next station" turned out to matter more than I expected. Hit it once and you're in Reykjavik. Hit it again and you're in a small town in Hokkaido. The cost of leaving a station you don't love is one keystroke, and the next one is always a surprise.

That's the verb in the name. You don't have to choose. You hit the shortcut and let the world hand you a station.

Stations to try

If you want a starting point that's close to the Claude FM mood but pulls in more of the world:

• Lofi Radio Japan, Tokyo. Continuous lo-fi with occasional Japanese voiceovers.
• SomaFM Drone Zone, San Francisco. Ambient and dark ambient, no voices, deep focus.
• Radio Nova, Paris. French talk and curated music.
• BBC Radio 6 Music, London. English, but the curation earns the cost.
• Radio Aporee, Berlin. Field recordings from around the world. Rain in Bangkok, traffic in Lagos, a market in Tbilisi.

You can find all of these in Roam FM. You can also find another forty thousand you've never heard of.

When to use which

Claude FM works when you want to press one button and trust a curator. It's a fine default, and Anthropic will keep it that way.

Roam FM works when you want a wider world. When the same loop is wearing thin, when you want voices in a language you can't parse, when you want it as a Mac app instead of a browser tab.

You don't have to pick one. I leave Claude FM running on a tab some afternoons. Other afternoons I'm in a small bar in Tokyo, via a station I found by accident. Both of those are working hours.

If you've been enjoying Claude FM and want to try the rest of the world, Roam FM is here. Free to start, one-time purchase to unlock everything, native on Mac.
