Big Boi, Wale, Common, and Daddy Yankee are all contributing to the HBO-sponsored mixtape, which drops Friday and will be exactly what you'd hope: rap songs about Game of Thrones. Big Boi in particular is very excited about this project (and paycheck): "I'm really happy. I get to be part of the process of one of my favorite shows." Also, he's reading the books now, so he can find out what happens. Get in touch with Big Boi for all your Game of Thrones spoiler needs.
