It's probably not like this but there are some streaming sites that real time stream the broad radio spectrum at various locations around the world and you can tune in a particular radio station using a radio application that just works like the real thing.
It appears from my cursory investigation their APIs primarily help broadcasters send data to tunein. I haven’t found any way to programmatically interact with their services as a listener.
Are there APIs to trade lat/long (or zip) for radio stations’ streaming audio?
