It's definitely possible that Gotye—the guy who actually did the original version of "Somebody That I Used to Know"—has been overshadowed by the massive amount of remixes and parodies that have been uploaded to the Internet in recent weeks. From that Star Wars version to the one with those guys all playing one guitar together (we know you saw it), it seems half of YouTube is now dedicated to mixing up this song.
So Gotye has taken it to its natural conclusion, creating this brilliant and kind of eerie version made by putting together some of the remixes and parodies. It must have taken an incredibly long time to do, and the result looks great. Check it out.
