I want to know the answer to the following question:
What song did Beyoncé donate to the 2012 World Humanitarian Day campaign?
All the background I'm provided with is that "Beyoncé is also taking part in "Miss a Meal", a food-donation campaign, and supporting Goodwill charity through online charity auctions at Charitybuzz that support job creation throughout Europe and the U.S.". Is that enough to answer the question?
