I had no idea there are so many covers of the music from the opening of Game of Thrones.
I came across this one on BuzzFeed, done by YouTube user herbertcosta. I love the show, and I love cats, but I could never have imagined the two worlds coming together in such a silly fun way. I must have watched it five times in a row.
I heard this one too, which had been uploaded earlier back in January.
