Spotify To Create Custom Playlists Based On Your Heartbeat?

We spend hours mastering our playlists to match our mood. From chilling out to hard core work outs, custom music is about making our custom soundtrack. Spotify would like to take playlists to the next level by learning our behavior. Through the monitoring of things like heart rate, temperature and motion, Spotify would tailor our music, mood and playlists without any user interaction.
