It seems like everyone and everything has done some sort of a take on the annoying viral video "Gangnam Style" but this is the first metal version of the song that I've ran across. And honestly, it doesn't suck all that bad.

So I'm pretty sure that this dude has made a metal version of every stupid pop or internet song ever, and I'm happy he's still in business.  You can tell the dude just loves to play guitar and makes these awful songs much more palatable.
