After a total of six weeks atop the chart and more than 466 million YouTube plays as of press time, Macklemore and Ryan Lewis' "Thrift Shop" topped Billboard's year-end Hot 100 list, the third artist to top the list with their debut entry on the chart in the past four years. It's the first time a duo has been the year-end No. 1 since 1975.

The two also have a second song in the upper echelon, as "Can't Hold Us" featuring Ray Dalton comes in at No. 5. The two also grab the top spot as Billboard's top new artist, while Bruno Mars dominates 2013 as Billboard's Artist of the Year.
