" As opposed to most Internet radio stations, which either
simulcast existing programs or otherwise feature preselected
playlists, Pandora streams customized stations based on the
so-called Music Genome Project. Evolving since 2000, the Project is
the work of more than 50 trained musicians, who analyze songs via
"up to 400 distinct musical attributes, encompassing melody,
harmony, rhythm, etc."
"According to Pandora, this information is used to build
playlists based on musical similarity. By simply entering a
favorite song or artist, a listener is "instantly launched into a
personalized listening experience," and can create up to 100
personal radio stations, the company says.
"Pandora, which claims to have a user base of more than 18
million registered listeners, plus major national advertisers, is
usually heard via personal computers, but there are also software
clients for smartphones such as Windows Mobile devices, Apple's
iPhone, and RIM's Blackberry. The mobile clients rely on a user to
create personal radio stations via their PC, but can then log onto
Pandora and play the stations back from anywhere."
