JSON files
JSON is a data representation format derived from Javascript (the browser embedded programming language for websites). Streamtuner2 uses it to store it's configuration and radio station data files.
The MIME type of these files is application/json and they often look like:
[ { "title": "Station title..", "url": "http://1.2.3.4:8000/", "homepage": "http://radio.org/", }, { "title": "second" } ]
