The most dramatic change to the Zune software experience is the opening Quickplay page. From here, all your latest downloads are shown right up front, along with recently played items and content that you've pinned to the page, either through the software or from your Zune HD.
A smaller row of icons below the Quickplay bar shows off your Smart DJ playlists. During the Zune software setup you'll be prompted to name a few of your favorite artists, which Zune will later use to create your first Smart DJ playlists. You can think of these playlists as a hybrid of Apple's Genius playlists and an online streaming music service like Pandora. To create a Smart DJ playlist, all you need to do is type in the name of an artist or band, and the Zune software will ping its databases to find similar music in your collection. For Zune Pass music subscribers, the Zune software will not only look through your music library, but also pull unlimited streams and downloads of similar music from its Zune Marketplace music catalog.
