claude /radio: Play Focus Lo-Fi Radio While You Work

Many people open a separate music app to get immersed in coding. But what if you could play focus music right inside Claude Code? With a single /radio command, a lo-fi radio opens in your browser, letting you easily set the mood for work.

Definition (What It Is)

/radio is a command that opens a lo-fi radio in your browser. Lo-fi is a music genre with calm, repetitive beats; it has no lyrics or only faint ones, so it's often used as background music for focus.

Without having to find and open a separate music app, you create a focus music environment in Claude Code with a single command line.

How to Use It (By Difficulty)

Basic — Playing the Radio

/radio

Type this single line and a lo-fi radio opens in your browser. Focus background music starts flowing, so you can just continue working. Volume control or turning it off is done in the open browser tab (the page in your internet window).

Real-World Example

When doing work that requires focusing for a long stretch, playing background music with /radio is great for covering surrounding noise and getting immersed. Without breaking your flow by opening a separate music app to pick songs, you can set the mood right within your work environment.

Taking It Further

Being able to play background music easily means you can freely set the mood for work. If you make turning on /radio during focus-needed time slots a kind of start signal for work, you can also use it as a sort of "focus mode switch."

Summary

/radio is a command that opens a focus lo-fi radio in your browser. Typing it makes calm background music flow, which is great for immersing in work. Without opening a separate music app, give it a light play when you start a long task.
