(NEW YORK) -- Adele's album 21 spends yet another week at number one on the Billboard album chart.
All told, it's been on the top for nine non-consecutive weeks. In the history of the Billboard album chart, only 11 other albums by female artists have logged that much time at the top.
But 21 is not expected to be on top for much longer. Lady Gaga's new album Born This Way is expected to blast onto the chart next week with projected first-week sales of 800,000 to 850,000 copies.
