We recently reported on the Slacker Radio redesign, and the company is keeping the freshness going, debuting on the Xbox 360 today. You can download the Slacker app for free, and you've gotta be an Xbox Live Gold subscriber in the US or Canada for the privilege. You get the same overhauled color scheme, music guide, and Kinect voice controls. Head over to the Xbox Live Marketplace to grab the 116 MB download.
