Gaga had tried her best to kill 90's pop sensation out there.
Last year, Aguilera went down but when it comes to Britney... I think the world still love her and she has a huge fan-base. Some people call she's a flop due to only 600k of Femme Fatale sold in U.S. But, hey.. femme fatale leaked a month before the release date. 600k is not bad at all. The album will sell, all her singles doing so well this year. I got nerve to say the album will hit 1M before the end of the year.
I Wanna Go just cracked Top 30 on iTunes in less than 24 hours.
Her Femme Fatale tours sold out so far and having great reviews.

I may call her 'not talented' as some artists out there, but she does her things correctly. That's why people love her. And femme fatale sold over than 2M worldwide. That's impressive to me.
