Echo Nest's API already powers hundreds of music apps (e.g. MTV, Music Hunter, Pocket Hipster, etc.). With new enhancements to its API, Echo Nest looks to expand its reach beyond the music industry by "us[ing] music to drive non-music apps." Echo Nest added "Taste Profile Similarity" and an "affinity prediction" system to its existing platform. With the new features, Echo Nest hopes to connect music listeners to other listeners with similar tastes and predict behavior unrelated to musical preferences.
