Gotye released a mashup video on Sunday, compiling all the YouTube covers from the past year—and there are a lot. He added a disclaimer:

“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’s probably right, but he’s also got the No. 1 song of the year. He can do as he pleases. Click here to watch Gotye’s latest music video for “Save Me.”
