Musical acts have a similar epidemiology as the flu. Both start out as small, localized phenomena and then gain momentum with surprising speed, until everyone is hacking up the same virus and every radio station is blaring the same tune. Google caught on recently and created Flu Trends, which tracks the spread of the flu by charting user searches for flu-related words. And a team of Israeli researchers have come up with software that uses similar logic to predict the next big musical act.
This “music trends” software tracks searches for songs or bands on Gnutella, a giant peer-to-peer file sharing network, and locates where the searches are generated. Since new bands often develop popularity through local gigs (”American Idol” is an exception), the software works because it can tracks momentum of grassroots movements. Based on the local ranking of the searches and how fast these rankings change, the software can predict the next breakout band.
