Zune 4.5 update now available

Hey Zune owners, head up—the Zune 4.5 update has just gone live, and it’s ready for you to suck down from Microsoft. As a refresher, here’s what you have to look forward to:

• Smart DJ integration on Zune HD
• Picks on Zune HD (personalized recommendations based on your listening habits)
• Browse the Zune Marketplace on TV when you dock your connected Zune
• Expanded video codec support, reducing need for transcoding

Of course, there are likely a bunch of bug fixes and all that to make things feel mo’ better. In addition to all that, the new 64GB Zune HD will be available in a week!
