Dance music phenomenon Baauer has landed a fifth week atop the U.S. pop charts with his catchy Harlem Shake.

The viral hit, which debuted at number one last month (Feb13), keeps MACklemore & Ryan Lewis from returning to the top with Thrift Shop for a fourth consecutive week.

Meanwhile, the rap duo becomes one of only four acts to top the Billboard Digital Songs countdown for at least 10 weeks - three weeks behind record holder Flo Rida, who ruled the chart with Low in 2007 and 2008.

Back to the Billboard Hot 100, and Bruno Mars scores another week at three with When I Was Your Man, Justin Timberlake's Suit & Tie rises to four and Rihanna's Stay rounds out the new top five at five.
