If there are any inaccuracies please correct me.

Adele slaying with the highest for any act two years in a row.

Adele and Taylor slaying

Carrie

First line should say Nov 1998 to Nov 1999

But slay.

Thanks
Edited.

Multiple reigns
Taylor-4
Britney-2
Adele-2 (25 will add 2 more)
Norah-2

Ugh. Taylor will pass Bey this year.

Taylor is mean. She needs to learn how to share.

Beys been #2 a lot though so it's still impressive.

She was #2 in 2003
#2 in 2006
#3 in 08 (behind Taylor and taylor)

The title should be Best Selling Female ALBUMS Each Year since a best selling female artist stat includes single success combined with album success in which Christina Aguilera owned Britney in 2000, and Norah in 2003.

Nov 2013-Nov 2014
Beyonce-beyonce
Wrong

Taylor gonna snatch it

Bey said in her 30s she'd release yearly right?
As long as 25 doesn't pop in. Next year will be hers.

I mentioned in the OP everything I was including.
I wouldn't use the word owned for 2000 tho
Britney was #2 right and not by a long shot either...

I find artists like Norah Jones and Alicia Keys to be most impressive since their music is less pop and mainstream.

Slay Britney

Actually quite a lot of the artists on the list weren't in hugely successful genres.
Enya
Avril
Norah
Alicia
Adele.

Taylor slaying with topping the chart for 4 years

The problem I have with this list is that it only includes Female artists. Some in this list like Adele and Taylor were the best selling artists of all genders and genres in those Billboard years. Period.
