# Magnatune is a label for independent music. It provides
# free access to a partial section of its reportoire as MP3.
# Using paid subscriptions, all albums are available in
# higher quality Ogg Vorbis or FLAC encodings however.
#
# You can listen to all albums and tracks freely. They're
# just interspersed with short "magnatune" voiceunders.
#
# For now this plugin just fetches the small highested
# ranked album list. Just an excerpt. The huge album list
# is a 70 MiB download.
