Users “scrobble” the music they listen to on their ipod or computer through a downloaded application that records what they listen to. The scrobbler then sends this data to Last.fm’s servers. Last.fm compares user data to arrange personalized radio stations based upon your favorite music. The engine produces a station by grabbing music from other users’ whose taste is similar to your own. Additionally, users can have a radio station made around a single artist. These stations are created by recommending music that other users listen to in addition to your chosen artist. Additionally, Last.fm has largely incorporated social networking into its site. It has user profiles, events and widgets for your website. This is quite appropriate considering recommendations and stations are generated using communal data.
