• Make sure you are running a *nix system
• Make sure you have installed mplayer
• Open /home/your_user_name/.mplayer/config, and add "lirc = no"
• run "python filename.py"
• NOTE: Since the url for each song will be deactivated after 20 minutes, we run 5 songs each round, and use a loop to maintain.
