• artist - search for artists by name, description, or attribute, and get back detailed information about any artist including audio, similar artists, blogs, familiarity, hotttnesss, news, reviews, urls and video.
• song - search songs by artist, title, description, or attribute (tempo, duration, etc) and get detailed information back about each song, such as hotttnesss, audio_summary, or tracks.
• track - upload a track to the Echo Nest and receive summary information about the track including key, duration, mode, tempo, time signature along with detailed track info including timbre, pitch, rhythm and loudness information.
