Not surprisingly, it's called Global Breakfast Radio, and it streams 250 stations on its site, with one provision: it has to be breakfast time at whatever location is playing. You don't get to choose - they do.

As I post this, they're playing KVOQ in Denver, where it's just after 7:50 AM. Next hour features a station from El Salvador. It also includes a map of where the sun is just rising everywhere around the world. A separate page has an outlet from Saskatoon, while promoting an all Cajun station in Louisiana as the next offering. 

It's an odd concept but also strangely compelling - especially since morning radio is usually the best a station has to offer.

From their "About Us' page:

"The sun is always rising somewhere; breakfast is always just about to happen. Dinner time in Dakar is breakfast time in Brisbane. And in the background of breakfast is radio, soundtrack to a billion bowls of cereal or congee, shakshuka or api, porridge or changua.

"Global Breakfast Radio aggregates radio stations from across the world, constantly streaming broadcasts from wherever it’s breakfast-time right now. It’s the equivalent of a plane flying west with the sunrise, constantly tracking the chatter and music of people across the planet.

"In some small way, Global Breakfast Radio hopes to be a way of travelling globally through the medium of radio. It’s about the leap of imagination you make when you tune into a broadcast from a station hundreds or thousands of miles away – and for a time you hum the same song as a butcher in Memphis, a taxi driver in Jerusalem or a lawyer in Jakarta."

You can hear what's playing this hour here.  

An article in Smithsonian Magazine explains how the originators created the algorithm that keeps this breakfast being served.
