I've seen a lot of times "BOMT" with 28M copies
I've seen "Britney" with 15M
and I saw recently on a show on E! , they stated "Circus" has sold "4M and counting".
I've also seen a lot "Blackout" with 3,1M claimed sales.
but IMO ... BOMT hasn't sold more than 23 or 24M copies , and there's no way "Britney" has sold 15M copies, 10M seems the right number for that album.
