Why focus music belongs in a browser extension.
Every other way of getting focus music has friction. YouTube buries your tab in autoplay suggestions. Spotify wants a login and an algorithm vote. A focus music browser extension lives in your toolbar — one click, no surface area for distraction.

01
It survives a closed tab
Audio runs from the extension itself, not a tab you can lose. Close everything — the music keeps playing while you write, code, or read.

No feed to scroll
Eight curated stations. No "made for you" recommendations, no autoplay rabbit holes.

How focus music differs from a Spotify playlist.
"Lo-fi beats to study to" started on YouTube and migrated to Spotify focus playlists. Both are fine, but they have a structural problem: they live inside apps that want your attention. The playlist plays — but recommended-for-you sidebars, podcasts you might like, weekly mixes, social feeds, and the daily mix algorithm are all one tab away.
A focus music browser extension is the opposite. It's tiny on purpose. It cannot become a feed because it has no surface to feed you on. Press play; the player vanishes; the work begins.
FAQ.
What stations do you consider focus music?
Anything instrumental and rhythmically steady — meaning no vocals competing for your language brain, and no sudden BPM jumps that break flow. In Tonearm that's Groove Salad, Beat Blender, Space Station Soma, Drone Zone, and Deep Space One. Coding-leaning options are on the music for coding page.
Why a browser extension instead of a tab?
A tab is mortal — you'll close it accidentally, refresh it, or lose it under twenty others. Browser extensions have a background-script audio pipeline that stays alive regardless of which tabs are open.
Is it really free with no premium tier?
Yes. The streams come from public radio feeds (mostly SomaFM, which is listener-supported); we curate and present them. No login, no in-app purchases, nothing to upgrade.
What about ambient sounds — rain, café, white noise?
That's a different category. We cover ambient music (Drone Zone, Deep Space One) but not ambient nature loops. See ambient sounds for focus.
