Danceability - The Echo Nest defines danceability as the ease with which a person could dance to a song, over the course of the whole song. We use a mix of features to compute danceability, including beat strength, tempo stability, overall tempo, and more.
Duration - The duration of the track in seconds.
Energy - From the Echo Nest API documentation: The feature mix we use to compute energy includes loudness and segment durations.
Key - From the Echo Nest API documentation: the estimated overall key of a track. The key identiÞes the tonic triad, the chord, major or minor, which represents the Þnal point of rest of a piece
Loudness - From the Echo Nest API documentation: the overall loudness of a track in decibels (dB). Loudness values in the Analyzer are averaged across an entire track and are useful for comparing relative loudness of segments and tracks. Loudness is the quality of a sound that is the primary psychological correlate of physical strength (amplitude).
Liveness - From the Echo Nest API documentation: a number between 0 and 1 that gives a measure of how ÔliveÕ we think the song is. The higher the liveness the more likely the song is a live song.
Tempo - From the Echo Nest API documentation: the overall estimated tempo of a track in beats per minute (BPM). In musical terminology, tempo is the speed or pace of a given piece and derives directly from the average beat duration.
Time Signature - From the Echo Nest API documentation: an estimated overall time signature of a track. The time signature (meter) is a notational convention to specify how many beats are in each bar (or measure).
