The Moody Blues close
In Online Innovation
Tired of trying to put together the perfect mix to match your mood ? Then waste no time in installing Moody This little plug in lets you tag your music against a mood, so that you can then with a push of a button play back the happy intense songs or the clam sad songs... depending on what stage of the office Christmas party you are at.
The only thing that this seems to be missing is a central database of mood tagged tracks, so you don’t have to bother tagging your collection.
