More importantly you need the `update_streams()` method to fetch station lists. It receives a `cat` parameter, for instance `"Pop"`. Then do whatever API query or website scraping (regex/pyquery) is necessary to populate a list.

Most plugins will return a list of dicts like:

     {title: Radio123, url: http://pls, genre: Pop, playing: Song123}

The title is required, and the streaming URL of course. Other fields are mostly optional. (Received data gets stored internally in a `streams={}` dict.)
The title is required, and the streaming URL of course. Other fields are mostly optional.

   * Standard fields are: genre, title, url, playing, homepage, bitrate, listeners, favicon. Internal fields are: state, deleted, favourite.
   * Standard fields are:

        * <kbd>genre</kbd> - the category name
        * <kbd>title</kbd> - station title
        * <kbd>url</kbd> - streaming url (to pls or m3u resource)
        * <kbd>playing</kbd> - currently playing song, if any
        * <kbd>homepage</kbd> - station homepage
        * <kbd>bitrate</kbd> - (int) audio bitrate (like 128)
        * <kbd>listeners</kbd> - (int) number of listeners
        * <kbd>favicon</kbd> - url to favicon, if any
        * <kbd>format</kbd> - to set a custom audio format (audio/ogg)

   * Internal fields are: 

        * <kbd>state</kbd> - a gtk icon
        * <kbd>deleted</kbd> - strikethrough for deleted entries
        * <kbd>favourite</kbd> - add a star for bookmarked stations
        * <kbd>search_col</kbd> - search color
        * <kbd>search_set</kbd> - search state

   * With a `datamap=[]` declaration custom field names could be displayed.

   * Often you just want to rename the column titles however per `title=dict(listeners="Whatever")` in the class declaration.
   * Often you just want to rename the column titles however - per `title=dict(listeners="Whatever")` in the class declaration.

Received station lists get stored internally in a `streams={"Pop":[...]}` dict, and cached in the `~/.config/streamtuner2/cache/` directory of course.

There's also a `config=[]` list, in case your plugin needs to keep some settings. (For example an API key.)

The `has_search` class flag permits live server searches. If one is issued, the `update_streams()` method will be called with `cat=None` and `search="Find me maybe"` set instead.

  * Other class options include `listformat="audio/x-scpls"` for declaring the station URL mime type (here `pls` for example).
  * And `audioformat="audio/mpeg"` for the audio mime type.
  * While `current=""` and `default="Pop"` can specify which category is visible per default, or currently active. (Both will be retired in later versions. More a clutch for current Gtk handling.)
  * Other internal fields are listed in `channels/_generic.py`
