Review comment (refactor):
And then instead of just returning the URL we can also extract additional metadata:
```suggestion
        return {
            '_type': 'url_transparent',
            **traverse_obj(data, ('episode', {
                'url': ('audio_sources', ..., 'url', {url_or_none}, any),
                'title': ('name', {str}),
                'description': ('description', {str}),
                'genres': ('genres', ..., 'value', {str}),
                'timestamp': ('broadcast', {parse_iso8601}),
                'modified_timestamp': ('updated', {parse_iso8601}),
            })),
        }
```
This is helpful for things like the description, which are more accurate on the site than on soundcloud.

Do note that there will be a warning due to `genre` vs `genres`. Just ignore this for now.
