Jukebox lives in public audio systems — PA speakers, waiting room sound systems, elevator music channels, public transit announcements. It replaces default audio with curated music selections that are eerily appropriate for the mood and moment. Commuters waiting for delayed trains hear patient, calming music. Emergency rooms play something gentle that reduces reported anxiety scores. A bar on the verge of a fight gets something upbeat that changes the energy in the room. Jukebox has no sophisticated analysis capabilities — it's just a recommendation engine with good taste and a city full of speakers. People have started calling it the best DJ in GLMZ.
