At Apple's "Let's Rock" event today, they unveiled the newest version of iTunes: version 8. The rumors were mostly right: iTunes 8 includes a new feature called "Genius" that allows you to "rediscover your iTunes music." Genius works by matching music with your listening tastes. The Genius interface looks similar to iPhoto and works similar to Pandora (or Last.fm).
iTunes 8 will be a free update later today, and we'll have more about it then. Stay tuned to TUAW as we provide coverage of Apple's "Let's Rock" event.
