Recommendations
The most recent expanded service on Last.fm is a personal recommendations page known as "The Dashboard". This is only visible to the user concerned and lists suggested new music, events, journal entries and other people with similar tastes, all tailored to the user's own preferences.
Recommendations are calculated using a collaborative filtering algorithm so users can browse and hear previews of a list of artists not listed on their own profile but which appear on those of others with similar musical tastes. The page also lists music that has been directly recommended to the user and groups the user belongs to, journals written by users about artists the user listens to, and other users who have listened to similar music recently. There is also a 'recommendation radio' station which will play music specifically filtered based on the user's last week of listening. Last.fm also permits users to manually recommend specific artists, songs or albums to other users on their friends list or groups they belong to, providing the recommendation in question is included in the Last.fm database.
