First up is PSY, who, after some key promotion from Jimmy Kimmel, saw this new new track featuring Snoop Dogg, "Hangover," quickly rack up 12 million views. Charli XCX's "Boom Clap," meanwhile, has been a regular on the Trending 140, thanks in part to the fact that its in the hit film "The Fault In Our Stars."
