A Radio Station Just for You - New York Times

A Radio Station Just for You - New York Times: "Currently, the most compelling online radio is interactive. Services like Pandora, Last.fm and Slacker evaluate your musical tastes, then serve up a continuous stream of programming to match. They mix familiar songs with new material you might like. They all do it by harnessing the technological forces of social networking, data mining and music analysis, though each uses a slightly different technique."
