grit
an ugly force for good
I think it's a cracking idea. A really cheap way to get thousands of people to hear their ad for little cost to them while the buskers get a bonus.

Well done the coke marketing department.
That was pretty much my feeling on the news, its quite a clever little marketing ploy from the Coke's perspective.
