Either it continues to make "pop" as in the good old days, is so but eventually boring, because it is always the same and so win any new fans, OR it is evolving as it once Madonna did, moving with the times and fits to the current trend to sometimes. You can now decide for yourself what you will find it better!
My personal opinion:
If I remember back to "Femme Fatale", I must say that I liked the music, but at first but something was disappointed. It pulled a thread through the album, because the style was very dance-heavy and there were no ballads - more light something in his head remained personally with me not. One course had to get used to the first "new" Britney, I thought was the R'n'B-influenced singles like "I'm a Slave 4 U" or Piece of me "definitely better than" Hold It Against Me " and consorts.
With "Britney Jean" is different: Surely some dance-heavy tracks are also included again. I also had to start fear after I heard "Work B! Tch" that the album only this has a style. But ever since the - in my opinion - absolutely brilliant "Perfume" I had no more doubts: Britney has thrown here a colorful mix of all kinds of music together - and I like it! "Tik Tik Boom" comes on with slight R'n'B beats, while "Body Ache" 'Til It's Gone "are etc. very dance heavy. "Passenger" and "Alien" are great pop tracks and ballads like "Do not Cry" and "Hold on tight," are simply wonderful! About the lyrics, which were also criticized here, we have to be unable to talk - you hear only once "Perfume" - I do not know what it would be wrong with it.
With all due respect: Who can ask for hits like or "It Should Be Easy" sit in chairs ?? "Work B tch!" I do not in any case!
5 stars for Britney, who has been brave enough to bring a very mixed disc on the market - I'm excited !!!
Do not forget: Haters gonna hate! ;)
