This is a rap about Game of Thrones. Not the TV show, but the books, as rapper Dominik Omega explains in the intro. If you haven’t read all the way through A Dance with Dragons yet, then you might not fully understand this song’s outrageous awesomeness, but if you have, I highly suggest you listen, if not read the lyrics in the YouTube description as well. It’s so good I feel like GRRM should include it as a bard’s song in The Winds of Winter or something. Or maybe Sam can find it on an ancient scroll at the Citadel or something. It’s just that good, dammit. Thanks to GenericGlobula for the tip.
