Teenage Dreams reenters the BB200 (after being off for only 1 week ) at 164. It should get a big boost next week with the Christmas sales in. Also, it officially is on the 2014 charts. For an album that started in 2010.
I believe this should make it 10 weeks in the T10 for PRISM. A breakdown of the currently relevant divas and their # of studio albums to reach that mark:
10 wks T10: Taylor, Madonna 4
Beyonce, Miley (or 0) 3
Alicia, Britney, Pink, Katy 2
Kelly, Christina, Gaga, Rihanna 1
