Related to my earlier post about selling statistics, here comes along a new tool that allows you to visualize that data in a new way (and make decisions with it).

The service is called Moody and it is in the category of iTunes enhancers. Using a color-coded tagging system, Moody filters songs according to your mood. You can select our own color indicators to futher personalize the experience.

It is free and you can donate to the developers, if you are in the mood.
