I managed to accidentally stumble upon this. The I Am Campaign has this deal with Carolyn Malachi's song "Free Your Mind" where their corporate sponsors will donate enough money for an hour of school for kids in East Africa every time the song is played on YouTube or someone buys the song from, say, Google Play. Even better, the song's pretty good and definitely catchy.

So what do you say? Should we try and make this thing go viral? http://youtu.be/ResqPkcg1pE

The song starts about thirty seconds in, btw.
