It seems like everybody and their mother has done a cover of Gotye's "Somebody That I Used to Know." But this month, the Australian singer-songwriter created the mother of all covers, "Somebodies: A YouTube Orchestra." The megamix is a supercut of dozens and dozens of clips that were posted online. "Reluctant as I am to add to the mountain of interpretations of 'Somebody That I Used to Know' seemingly taking over their own area of the Internet, I couldn't resist the massive remixability that such a large, varied yet connected bundle of source material offered," he wrote in the video's description. Wanna watch the source material from beginning to end? Gotye listed all of the videos he used on his blog.
