I like my receipts to be from official and credible sources that I can cite in a decent college research paper so let's move to IFPI, shall we?
Lady #1Ga - 5 IFPI entries - 2.5 albums
Beysus - 3 IFPI entries - 3 albums (IFPI's reports for digital sales have only been around since 2006-7)
Anglo-Saxon Perry - 2 IFPI entries - 2 albums
Rihfadna - 2 IFPI entries - 6 albums and a billion collaborations
