Psy- “Gangnam Style” – 2.49 billion views

Originally released on July 15, 2012, “Gangnam Style” quickly became a cultural and global phenomenon, anchored by an arguably catchy tune and a ridiculously bizarre, delightful, and visually engaging K-pop video. And oh yes, did we mention it came with its own dance? Thankfully, the dance has since gone the way of the dodo, but “Gangnam Style” still holds the record for being the fastest song to ever accumulate 1 billion YouTube views, having achieved the feat in only 160 days.

But Psy might want to watch is back as Adele’s song “Hello” has already amassed nearly 950 million views since hitting YouTube in October.
