Glee Does Gangnam Style

As much as I dislike Gangnam Style it just keeps getting more and more popular. Why the heck is that? Anyways, it has gotten to the point where now Glee, the American TV musical show, is using Gangnam Style in their next season. I just don't think that Glee and Gangnam go together and not just when Blaine tries to put them together in the video.
