General Motors has expanded its penetration of XM Satellite Radio as a standard factory-installed feature, across its 2008 model year vehicles.

Now all Buicks, Hummers and Saabs will have XM as a standard feature for the 2008 model year.

In addition, XM is also now widely standard on the all-new 2008 Chevrolet Malibu, Silverado, Tahoe, Cobalt, Corvette and Impala; Saturn Vue, Outlook, Aura and Sky; GMC Acadia, Yukon, and Sierra; and Pontiac G5 and Solstice models among others.

To date, GM has produced over 6 million vehicles with XM, and XM is available today on more than 50 model year 2008 GM vehicles.

Every new General Motors vehicle with factory-installed XM comes with a free 3-month trial subscription.

Kawasaki will be offering motorcycles with satellite radio, for the first time, this fall through a partnership with XM.

Kawasaki will begin with including XM, as an option, in its new Premium Audio System on its Vulcan 1600 Nomad touring model.

True to its name, the Kawasaki Vulcan 1600 Nomad is a travel ready touring-cruiser motorcycle with a 95-cubic inch V-Twin and excellent riding dynamics.

"This Premium Audio System is a high-quality system built to Kawasaki's specifications designed to greatly enhance our customers' ownership experience. As the pioneer in satellite radio, XM represents a terrific value-added feature to the system," said Jim Williams, Kawasaki's senior manager of accessories.

Back in mid-2005, XM announced a partnership with Harley-Davidson, and a year later offered an aftermarket solution: the Road Tech AL20.

Slacker and Spin Magazine have partnered up to bring together a free Slacker Spotlight Station called "Spin Punk."

The "Spin Punk" Slacker Spotlight Station coincides with what Spin called its "ultimate punk issue." Entitled "1977: The Year Punk Exploded!" the October edition of Spin (on newstands right now) includes an article chronicling the rise of punk, interviews with the Sex Pistols' Johnny Rotten and the Clash's Mick Jones, a definitive timeline of punk in 1977, and much more.

The Slacker Spotlight Station features the most influential punk music spanning over 30 years handpicked by editors at Spin. It also lets listeners view cover art and read profiles of each artist and album to further enhance the punk music experience.

"Spin has always been about giving our readers a new perspective on music," said Malcolm Campbell, publisher of Spin. "By partnering with Slacker, our '30 Years of Punk' issue provides a new take on the evolution of Punk. Readers can now simply click and listen to the music that has left an indelible mark on our culture."

Since Slacker has an embeddable widget, I've embedded the Spin Punk station into Orbitcast... check it out after the jump, or follow the link below to check it out on Slacker.com.
