# LiveRadio.ie, based in Ireland, is a radio station directory. It provides
# genre or country browsing (not in this plugin). It accepts user submissions.
#
# This channel loads their station logos as favicons, provides a live search.
#
# However, station URLs have to be fetched in a second page request. Such
# the listings are unsuitable for exporting right away. OTOH the website is
# pretty fast; so no delay there or in fetching complete categories.
