I love it all....it was fantastic on first listen and now I cannot tell you how much I lADORE it! The only track I skip is “Hold it against me" which actually sounds lower and better on the album than the single, I am so glad all the other songs are better than HIAM. I LOVE Criminal and I think I Wanna Go is another super hit like TOXIC! I hated BFB at first and now I think it is a genius track for the album. I love the vocals on the album which are there to be an “Instrument” played in the songs. Britney is the ONLY singer that uses her voice in this way! She bends the words and mispronounces them to fit the "sound " of the song! Britney's timing is impeccable, (this is why she is an outstanding dancer..... her sense of timing is like nobody else's ...I have noticed how she can join a group of dancers halfway through a dance and she does it instinctively not in a learned way) and this is such a huge part of her appeal! Her sense of rhythm NEVER lies to her and that's why she can always pick the RIGHT songs to sing and record. She knows what people will FEEL!
