In the scrAPI version, radiolists are not processed. They could be: the following regex - if inserted immediately after the playlists line - picks up radiolists:

                   r'(?:(?P<radiolist>RD.*?)\&)?'

In the bs4API version, radiolists are picked up with playlists, but with an 'id' that starts with 'RD' instead of 'PL'. To avoid processing them (or anything else that is returned that isn't a 'PL' playlist) the code includes this hack:

                    # don't append radiolist playlists
                    if str(item["id"]["playlistId"]).startswith("PL"):
                        items.append(item)

But what to do with a radiolist, once it is picked up?
