Roughly a week after Eminem, Dr. Dre and 50 Cent broke NielsenSoundScan‘s record for opening week download sales [click to read], Flo Rida has broken the record yet again with his single, “Right Round.” The Miami-based rapper has sold over 636,000 digital downloads of his latest single, beating the Aftermath trio’s mark of 467,000.

Record-setting digital sales of his material is familiar territory for Flo Rida, after seeing his 2008 single, “Low” become the highest-selling digital single of all time, with sales upwards of 4 million copies [click to read]. “Right Round” will be included on Flo Rida‘s sophomore effort, R.O.O.T.S.
