# 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.
#
# Audio URL lookup is done in urn_resolve action handler now,
# so only happens on playback. Which of course won't allow for
# exporting/bookmarking etc.
# Now fetches up to 5 pages (20 entries each).

# · Normally just provides a web player, but used to show .pls links for various
#   players. Meanwhile this is hidden, but the playlist generator is still
