Microsoft has released the updated Zune 4.0 software with an alternative menu scheme called Quickplay. This new interface is designed to connect you with your favorite and most relevant content within one touch. It neatly organizes your "pins" (think of favorites), recent history and newly added music, pictures, videos, podcasts, etc.
The Quickplay menu is the new starting point on the PC software side of the things as well and includes thesame categories as on the Zune HD; pins, history and new. We have big new feature you will find on that screen called Smart DJ. Pick an artist and the Zune software will create a playlist based on that choice, pulling music from your collection and the Zune Marketplace.
Zune 4.0 also added an internet browser to the Zune HD so you can update status on the fly. As for existing Zune devices, they will get a light firmware update for integration with the new PC software. This is a major update from a hardware standpoint, so many of the device features like HD radio, apps, Quickplay and movie rentals are exclusive to Zune HD. Existing Zune devices will be able integrate seemlessly with the new Zune PC software, including the ability to sync and play purchased movie content.
