Forget HD television programmes being available to download, forget the new iPhoto-like album display (although a welcome addition), forget the new ‘Visualizer’, Genius is the best new feature to be introduced.
Genius is a neat feature that allow automatic creation of playlists based on the track that is currently selected. These playlists can be refreshed in an instant and saved for later.
Steve Jobs has assured that the information that is collected weekly via the Internet is totally anonymous. Without this assurance I doubt many people would partake in the use of Genius. The information that is used by Apple includes your playlists, track names, ratings and play counts. All of this is combined with other iTunes users’ info to form a massive database of information makes Genius work.
