Let’s hear it for the dancing feet. Songs to dance by. Developed by students at the MIT Media Lab and owned by Spotify, Echonest uses digital processing technology to identify attributes of songs, such as valence, instrumentation, and key signature (pdf). The company created a proprietary algorithm to determine the “danceability” of a song based on its tempo and beat regularity. The calculation emphasizes the ability to dance throughout the whole song, so a bridge that even briefly changes the mood is highly penalized.
