2009
2010
and it seems like she is the it girl of 2015

Madonna's COADF sold 10M and Hung Up was #1 in 41 countries.Her tour grossed $227.77M.She kind of owned late 2005-2006

Pre 2000.Looking at sales she was the best selling female artist of 80s.So 80s+1990.

She also has the best selling album of 1986(True Blue) and 1990(The Immaculate Collection).Globally.

Kelly C owned 2005. You tried tho

Mariah probably had a few years in the 90's.

Yes, she was 1 of the 3 in 2014.

2008.



Best selling album of the year (surpassing total worldwide sales of 10 million) and 5 GRAMMYs.

2008 - Leona

One of them in 2010, 2011, and 2012.

Hilary 2003 with her album debut and Lizzie Mcguire, she was the Teen Queen.

Bleeding Love and Umbrella were very big hits, but neither artist had anything else.

2007 was Nelly Furtado's year (multiple hits, second best selling album), as well as Amy's (best selling album of the year).

Nelly can have '07. Amy will have 2008 as she won her GRAMMYs, as well as the best selling album of the year (again!).

Avril: 2002

Taylor:2009, 2014, 2015

Amy Winehouse (2007-2008), Adele (2011-2012), and Taylor Swift (2014-2015) each with back to back years at the top.

Talent surely does win, especially if you write your album yourself. Not many artists can say that!
