# Just a standard genre/country radio directory. Not very
# suitable for extraction actually, because it requires a
# second page request for uncovering the streaming URLs.
#
# This is done in row(), so only happens on playback. Which
# of course won't allow for exporting/bookmarking etc.
# And the server is somewhat unresponsive at times. Only one
# page (50 stations) is fetched.
