#
# REQUIRES the gmusicbrowser music player to be installed on your computer.

# The playlist submenu is designed to pull all .m3u files from the ~home/$USER/.config/gmusicbrowser/ directory.
# Therefore, you must create this folder and export your playlists to this folder.
# To enable song information to display, you must enable the NOW PLAYHING plugin in gmusicbrowser.
# Add this to "command for when playing song changed": tee /home/$USER/.config/gmusicbrowser/nowplaying.info
# Change $USER to your actual username. Tick the checkbox for send title/artist/album in standard input.
# You also should go to Preferences > Misc. and tick the checkbox for remember playing position between sessions.
# This allows gmusicbrowser to remember the song it was playing within the playlist upon exit.
