Scrobble
Last.fm is a music website, founded in the United Kingdom in 2002. It claimed 30 million active users in March 2009. On 30 May 2007, CBS Interactive acquired Last.fm for UK£140m (US$280m).
Using a music recommender system called "Audioscrobbler", Last.fm builds a detailed profile of each user's musical taste by recording details of the tracks the user listens to, either from Internet radio stations, or the user's computer or many portable music devices. This information is transferred ("scrobbled") to Last.fm's database either via the music player itself (Rdio, Spotify, Clementine, Amarok) or via a plugin installed into the user's music player. The data is then displayed on the user's profile page and also compiled to create reference pages for individual artists. By April 2011 Last.fm reported more than 50 billion scrobbles.
The service is free for users in the UK, US, and Germany; users in Canada, Ireland, Australia, New Zealand and Brazil require a subscription to use the radio service (€3.00 per month after a 50 track free trial). The site offers numerous social networking features and can recommend and play artists similar to the user's favourites. It also uses a Wiki system analogous to Wikipedia where users can share information about artists, tracks, and more.
