Many like them have long since depreciated. For some time, Miss Aguilera reenters ziehmlich "Dirrty" on. And it stands to reason to suspect that it strikes similar way as plastic music queen Britney Spears. In fact, however, better than me, "Back to Basics" like "Bionic". There are some that evil regurgitates me in this work: the album is in many parts not sexy but cheap. "Woohoo", a collaboration with Nicky Minaj, for example, acts of oral gratification. Other songs on the album grab "explicit" topics. That would not bother me to be, if it were just not as completely unique. So it all depends as I said just over cheap. You could have made it all much gallant and better with metaphors and paraphrases. One or the other song you do not like to hum due to the text. What's more annoying moaning on "Desnudate" an unimaginative "Prima Donna" and the really underground "I hate boys", which is simply embarrassing. There but fortunately also a wealth of great songs. As always, Christina Aguilera is working with the right people together. "Elastic Love" was written together with MIA and is a massive song, like a "rubber band". "I am" is a beautiful ballad that has contributed Sia and is available both on the Deluxe Edition. But not the only reason why I recommend buying the Deluxe Edition. Because at least 2 bonus songs are absolutely worth hearing. As would be the one the shimmering "Monday Morning". A Santigold collaboration and my favorite song on the album. And on the other hand would also be the same subtle but insistent call to "Birds of prey". One or the other may criticize that Christina Aguilera has vocally restrained ziehmlich. Personally, I find it very pleasant not continously abzubekommen full charge, as was the case with its predecessors. Great vocal use it still shows, for example, in the ballad "Lift me up", but not continuously, so that listening is not strenuous.
