In order to fake a radio, we need to stream radio content.
BBC Radio streams are playlist files, which contain
a link to a time-restricted audio stream.

Every few hours, the stream disconnects and you have to
download the playlist again to continue.

This downloads the playlists and parses for the audio end point.
