Introduction to Pandora

"We believe that each individual has a unique relationship with music - no one else has tastes exactly like yours." -Pandora

Many people have heard of Pandora- the website that creates personalized radio stations and takes away the stress of creating your own playlist or finding new music. Pandora is a website that provides a legal, premium, personalized radio service that allows the user to select a song that they want Pandora to create a playlist from. This allows the user to be exposed to a lot of new a different music that Pandora recommends from the original song the user began the playlist from. The user is then able to give a "thumbs up" or "thumbs down" to songs they like or dislike, therefore further personalizing the radio station to their preferences. But how does Pandora know what songs someone will like just from that one song that the user started with?
