#
#
# A modern alternative to ShoutCast/ICEcast.
# Streams are user-contributed, but often lack
# meta data (homepage) and there's no ordering
# by listeneres/popularity.
#
# OTOH it's every easy to interface with. Though
# the repeated API queries due to only 10 entries
# per query results make fetching slow.
