The first commercial partnering Taylor Swift and Diet Coke -- her favorite soft drink -- has debuted.  It's called "Music that Moves," and it shows how a solo activity like songwriting has the power to touch people everywhere.

 

 

 

 

 

In the spot, Taylor is shown writing her latest single, "22," , scribbling out lyrics in her bedroom, while sitting at a soda counter swigging a Diet Coke, and backstage at a fashion shoot.  The spot ends as the words "Stay Extraordinary" appear onscreen.
