Rapping for the Big Mac??

Mcdonalds is hoping to cash in with a Rapper saying the phrase Big Mac in the song&they have to approve it. now most Rap Songs today are about a Higher lifestyle&unlike say 20 years back the thought of hearing a Rapper mentioning a Big Mac today is like seeing Bill O'Reily Bopping His head at a Ludacris Video it ain't gonna happen likely. the economics of the Rap Game now has long ago surpassed Mcdonalds.for all the product placement that goes on within Hip-Hop I'm not seeing Big Mac's being pushed to the forefront. in a different era this would have been cool.thinking of all the Artists,lingo,images,etc... that have passed since Rap Music became the Cornerstone of Modern Pop Music&seeing a Icon as big as Mcdonalds just now getting Hip to wanting a Rapper or Rappers name drop a Big Mac seems so odd&Out of place.
