+# This setting controls the top directory which MPD will search to discover the
+# available audio files and add them to the daemon's online database. This
+# setting defaults to the XDG directory, otherwise the music directory will be
+# be disabled and audio files will only be accepted over ipc socket (using
+# file:// protocol) or streaming files over an accepted protocol.

+music_directory		"/app/music"

+#
+# This setting sets the MPD internal playlist directory. The purpose of this
+# directory is storage for playlists created by MPD. The server will use
+# playlist files not created by the server but only if they are in the MPD
+# format. This setting defaults to playlist saving being disabled.
+#
+playlist_directory		"/app/playlists"
+
+#
+# This setting sets the location of the MPD database. This file is used to
+# load the database at server start up and store the database while the
+# server is not up. This setting defaults to disabled which will allow
+# MPD to accept files over ipc socket (using file:// protocol) or streaming
+# files over an accepted protocol.

+# Audio Output ################################################################
+#
+# MPD supports various audio output types, as well as playing through multiple
+# audio outputs at the same time, through multiple audio_output settings
+# blocks. Setting this block is optional, though the server will only attempt
+# autodetection for one sound card.
+#
+
+# Use a fixed format for the HTTP stream because it cannot switch its audio 
+# format on-the-fly when the song changes.
+# See https://mpd.readthedocs.io/en/latest/plugins.html#httpd.
+# See https://wiki.xiph.org/Opus_Recommended_Settings#Recommended_Bitrates for
+# recommended Opus settings.
