PLEASE READ BEFORE EDITING or DELETING THIS ARTICLE   I figured out these sales totals by devising an equation to work out worldwide sales figures based on RIAA official US sales figures Only Elvis Presley The Beatles and Michael Jackson are official worlwide sales figures made public by these artists record companies This is the most accurate list possible and has been approved by music buffs and people in the industry Dont go changing this list I encourage people to add to it and turn the top  into a top  but do not change the sales figures of these artists allready on the list unless you have a better source In that case be my guest
