  Display songs currently playing in DeaDBeeF.
  
  Configuration parameters:
      cache_timeout: refresh interval for this module (default 5)
      format: display format for this module (default '[{artist} - ][{title}]')
      sleep_timeout: when deadbeef is not running, this interval will be used
          to allow faster refreshes with time-related placeholders and/or
          to refresh few times per minute rather than every few seconds
          (default 20)
  
  Format placeholders:
      {album} name of the album
      {artist} name of the artist
      {length} length time in [HH:]MM:SS
      {playback_time} elapsed time in [HH:]MM:SS
      {title} title of the track
      {tracknumber} track number in two digits
      {year} year in four digits
  
      For more placeholders, see title formatting 2.0 in 'deadbeef --help'
      or https://github.com/DeaDBeeF-Player/deadbeef/wiki/Title-formatting-2.0
      Not all of Foobar2000 remapped metadata fields will work with deadbeef and
      a quick reminder about using {placeholders} here instead of %placeholder%.
  
  Color options:
      color_paused: Paused, defaults to color_degraded
      color_playing: Playing, defaults to color_good
      color_stopped: Stopped, defaults to color_bad
  
  Requires:
      deadbeef: a GTK+ audio player for GNU/Linux
  
  Examples:
  ```
  # see 'deadbeef --help' for more buttons
  deadbeef {
      on_click 1 = 'exec deadbeef --play-pause'
      on_click 8 = 'exec deadbeef --random'
  }
