Microsoft provides a free upgrade firmware for its media player Zune HD this spring, and it is adding a number of features to the device that users of the desktop companion already know.

First up is Smart DJ, which like Apple’s iTunes Genius creates playlists of similar music. With a Zune Pass subscription service for music store online from Microsoft and the library, these lists will be populated not only your music library, but also catalog the Zune Marketplace, Microsoft said. If you do not have a Zune Pass subscription, Smart DJ will be withdrawn songs from his local library.

Second is Picks, another feature similar to Genius. According to the announcement Monday by Microsoft, “the Picks algorithm analyzes what you listen to and compares that to millions of other Zunes users to make personalized recommendations.” It is another feature already available in the Zune desktop software.

Third, Microsoft so that people can connect your Zune on your HDTV (via the dock) and music on the big screen. And finally, Microsoft is adding support for the video codec MPEG-4 Part 2 Advanced Simple Profile, including support for AVI and Xvid files.

Microsoft announced the update is coming “in the next few weeks.”
