# api: streamtuner2
# title: jamendo browser
# description: Jamendo is a license-free music collection and artist hub
# depends: json
#
# Now utilizes the Jamendo /v3.0/ API.
#
# Radio station lists are fixed for now. Querying the API twice per station
# doesn't seem overly sensible.
#
# Albums and Playlists are limited to 200 entries. Adding a cursor is
# feasible however.
#
# Tracks are queried by genre, where currently there's just a small built-in
# tag list in ST2.
#
#
# The v3.0 streaming URLs don't seem to work. Therefore some /get2 URLs will
# be used.
#

# Seem to resolve to OGG Vorbis each.
