Nerd bytes

Se me habia olvidado ya que tenia un blog nerdyyii...

Os dejo un scripcillo que se conecta a un music player daemon y publica lo que se esta todando ahi, en una cuenta MSN que este siendo usada por algun programa que use telepatia.

Probablemente sea buena idea transformarlo en un plugin...

simple, preciso y feo.. :P
