# Utilizes the Jamendo /v3.0/ API now completely. That means all tracks will
# be available as Ogg Vorbis per default.
#
# Radio stations are a fixed internal list. There's not much point in querying
# the API for them. (They're really just automated playlists, and MP3-only.)
#
# Genre lists for tracks are built-in, but give a good enough overview. There's
# no "related" lookup possibility yet in our station lists. (Might be feasible
# as plugin though, via [load more] button etc...)
#
# Per default Ogg Vorbis is used as streaming format. Track URLs can be played
# back directly. Playlists and albums now require a roundtrip over the action
# module to extract the JAMJson format into pls/m3u/xspf. (The previous v2 API
# retrieval is going to become inaccessible soon.)
