I'm creating an alarm clock with a gui using TKinter and python on my raspberry pi. When the alarm goes off I want it to start playing pianobar. I can do this easily enough, but I also want to display the name of the song on the GUI, and I cannot figure out how to get the current song being played. I have tried using pipes "|", and redirecting with ">" but I have gotten nowhere. Any advice will help.
How do I retrieve the current song name and time left from pianobar using python?

You need to use the event command interface. From the man page:
~/.config/pianobar:
~/config/event_command.py
This will write the song information to ~/.config/pianobar/nowplaying when a new song starts (there are other events available in the manpage). You can then parse that using your choice of tools to acquire the song title.
