Test your car's audio quality with iTunes playlist

General Motors audio engineer Matt Kirsch, who did the sound work for the Chevrolet Cruze, has developed an iTunes playlist that helps drivers test their cars' audio quality. The “10 Songs for an Audio ‘Test Drive'” playlist includes: “Don't Know Why” by Norah Jones “Diamonds and Rust” by Joan Baez “No One” by Alicia Keys “Hotel California” by the Eagles “Boom Boom Pow” by the Black Eyed Peas “Rock That Body” by the Black Eyed Peas “Hide and Seek” by Imogen Heap “He Mele No Lilo” by Mark Keali'i Ho'omalu (from Lilo & Stitch) “Bird on a Wire” by Johnny Cash “Packt Like Sardines in a Crushd Tin Box” by Radiohead While “Boom Boom Pow” and “Rock That Body” should have accurate and powerful bass beats, “No One” and “Bird on a Wire” should feature clarity in the vocals. Kirsch's playlist is available for download at http://tiny.cc/c2ach.

That combination is something Mercedes couldn’t resist as a PR vehicle, so they enlisted Dynamo, David Coulthard, a Mercedes SL63 AMG and an abandoned airfield to produce a new Dynamo illusion to promote the SL63 AMG.
