# Internet-Radio.co.uk/.com is one of the largest stream directories.
# Available music genre classifications are mirrored verbatim and flatly.
#
# The new version of this plugin alternates between PyQuery and Regex
# station extraction. Both overlook some paid or incomplete entries.
# HTTP retrieval happens in one batch, determined by the number of pages
# setting, rather than the global max_streams option.
