In one of the more recent Microsoft Sync commercials, a track is played that is a jazz horn type of sound. that for lack of better terms keeps “stepping up” and also kinda zooms and zips. I would dare to say it is a repeating loop, but just then it changes into more horn sounds.
it HAS been used in car commercials before, with a car zooming around a LED changeable road sign.
A little help here? 
Can you find a YouTube link or something?
UPDATE:
The commercial has the driver stating “Play Mocean Worker”
Itunes has “Mocean Worker” as the name of an electronic group. As far as I can tell, Itunes does not have the song for sale.
What Mocean Worker song is used in the Sync Commercials?
Here’s a link to the ad: http://www.lincoln.com/extras/tvads.asp?ad=10
Which I found on Mocean Worker’s website: http://www.moceanworker.com/
The song appears to be Right Now: http://www.amazon.com/Enter-Mowo-Mocean-Worker/dp/B0001MDQEO
Here’s some general info from Wiki
and a link to a Lincoln ad (not sure if it’s the right one)
Edit: same ad linked by GFactor above
That would be it.
Having a title / artist sure helpped, eh?
