Decibel launched its first API in 2011. Since the launch, Decibel has enjoyed success in becoming the fastest growing European company in the digital music sector. However, the massive growth falls short of Decibel's ultimate goal. Decibel hopes to enhance the consumer relationship with digital music and uncover the next generation in digital music services. In the end, Decibel aims "to become the industry standard for music metadata."
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.
