lol YES!!! That song was HUUUUUGE. But let's be honest, it was only so massive because of it's iconic music video (even Gangnam Style's video seems to pay homage to it in one part

). I'd say it was just as big as Toxic and Yeah! tbh.
The prime minister said he liked the song, the media went INSANE about it lmao.
Hung Up's instrumental seemed slightly inspired by it aswell.
