Output the filename of the current playing song

[Rene Maurer]

Hello

I am really very happy using dtas. There are some minor things I miss.
One thing is a shortcut to get the filename of the current playing song.
For example something like this: 

# COMMANDS

* current song [FILENAME] - output the filename of the current playing
  song or the song at the top if the queue in case the player is
  paused. If FILENAME is specified, the output is written to that file.

Best
René
