Our Buzz. Right Now.

To calculate our musical buzz at the moment, musical analysis data for the hottest tracks right now on Spotify is retrieved from The Echo Nest.
Our Musical Key. The dominant musical key among the tracks we are listening right now. It is determined through calculating the amount of sound mass (energy) present in each musical key.
Our Pulse. The (weighted) mean BPM of the tracks in the dominant musical key.
Our Mood. Determined through calculating the (weighted) center of mass of the (valence, arousal) data set that is associated to the tracks in the dominant musical key. The resulting point is mapped to emotional states which are represented by the color circumplex below, and the corresponding color is served in the background. The underlying framework for this procedure can be found in A circumplex model of affect, by James A. Russell.
