Are there open systems for selecting content based on collected statistics like last.fm?

Question

css

There is a task to offer the user tracks based on the tracks they have already listened to on the portal. All tracks in the portal database are tagged for a large number of items, such as genre, mood, etc. Is there any open source project similar to the last.fm engine that could be used, or peep general ideas, directions?

better use classes and opacity property
for animation use transition
