Last.fm - New Addiction

If you're a fan of music I recommend the site last.fm

It's a social networking site that picks out songs based on your past artist tastes.  It is an internet radio and music community.

You can view my profile and music tastes here.

Using a music recommendation system called "Audioscrobbler", Last.fm builds a detailed profile of each user's musical taste by recording details of all the songs the user listens to, either on the streamed radio stations or on the user's computer or some portable music devices. This information is transferred to Last.fm's database ("scrobbled") via a plugin installed into the user's music player. The profile data is then displayed on the user's profile page. The site offers numerous social networking features and can recommend and play artists similar to the user's favourites.
