XM subscribers, now you have XM Radio on Vista Media Center. XM officially announced the launch today in conjunction with the Vista release.

"XM is pleased to be extending its strategic relationship with Microsoft with the inclusion of XM Radio Online in Windows Vista," said My-Chau Nguyen, XM senior vice president for marketing programs and operations. "By working with Microsoft, we are expanding the availability of XM Radio Online, which provides an extraordinary variety of music choices, talk radio options, and exclusive programming such as 'Oprah & Friends.' The integration of XM Radio Online further enhances the music and entertainment experience offered by Windows Vista."

"Microsoft is pleased to be working closely with XM," said Mike Sievert, corporate vice president, Windows at Microsoft Corp. "We are thrilled with XM's support and excitement for the launch of Windows Vista and the 2007 Office system."

I'm an XM subscriber and tried it out this weekend, it works great, and the high bandwidth version sounds nice. As you can see from the screen shot the interface is pretty simple to use, and it's all controllable via the MCE remote.
