last.fm

Last.fm is a music website founded in the United Kingdom in 2002. Utilising a music recommender system known as "Audioscrobbler", Last.fm creates a detailed profile of each user's musical preferences by recording the details of the tracks they listen to, whether from Internet radio stations or from the user's computer or portable music devices. This information is transferred ("scrobbled") to Last.fm's database via the music player or through a plug-in installed in the user's music player. The data is then displayed on the user's profile page and compiled to create reference pages for individual artists.
