What's The Single Of 2012?

As Billboard approaches the cutoff date for its year-end charts, today they published the above recap of how many weeks each of this year's most popular singles have held the top spot. There have been relatively few #1 singles in 2012 due to four hits holding the pinnacle for nearly eight months in total. Maroon 5's One More Night is still #1 and appears to be headed for Single Of 2012, but Billboard's complicated system sometimes provides a surprise winner.
