The Zune 4.5 update we saw last week looked pretty good! More codec support, Smart DJ music discovery (similar to the iTunes Genius feature that's pretty stellar with a Zune Pass), and a few other fun features. It's available even sooner than we thought, so all you Zune owners go ahead and open up your Zune software on your computer and connect your Zune HD to get the latest and greatest.
