What is syncing?
When Moodagent is syncing, it simply connects to our servers to get high-definition track profiles for your songs. When Moodagent goes to work, it creates information profiles on music tracks that can then be clustered and compared in any number of ways (e.g. by mood, genre, instrument, beat, sound, decade, etc). So every track has a profile and because of that, you are able to create playlists based on moods and other variables.
