Airfoil

So i just discovered AirFoil. If you have and airport express setup at home it will eventually piss you off that you can only stream music in your house from itunes. Airfoil takes care of that issue. All you need to do is install Airfoil and you can stream things like Pandora over your home system. Pretty danm cool: http://rogueamoeba.com/airfoil/mac/
