2012 was the year of the viral single–from Gotye’s Peter Gabriel-esque “Somebody That I Used To Know” and Canadian import Carly Rae Jepsen’s “Call Me Maybe” to the world-conquering “Gangnam Style” from Korean singer Psy. These songs, and many of the big hits of this past year, mark just how interconnected we are, as they spread more through Facebook posts and memes than video rotation or radio airplay.
