So we were just told about this awesome application that will play music based upon your mood. Moodagent is an interactive playlist that catagorises music and plays them based on your current mood. I think this is a lot more fun then just hitting play on those other music apps that are popular right now.
With Moodagent you can down load it to just about any type of phone or computer. They have a free version and a paid version. The normal price for the paid app is $5 but right now for a very short time it is only 99 CENTS!
