Mood-based technology might zap us to better understand how music relates to human emotions. In their press release, Syntonetic says they’ve “cracked the emotional codes found in music to create an intelligent system that deciphers every musical property in a song, including moods and emotions, as well as musical genres and sub-genres, styles, tempo/beat, vocals, instruments and production features.” The way I see it, we’re only on the brink of emotion technology. App enthusiast Diego Balbuena says, “I do think that these type of programs can be the next killer app” but he stresses the importance of the apps being human-like. The more users that use the app, the more data they’ll have, and the better the algorithms will be. Happiness is a warm iPhone.
