Beyoncé 4 (Version collector)

This CD is awesome, Beyoncé returns to his R & B roots, the result may not appeal to everyone.
It is fairly quiet and the promo title "Run The World (Girls)" was in some way a "trap".
So I think the fans will like Beyonce but those looking for a CD that moves, it is not what you need.
The exclusive tracks are very successful, I love "Lay Up Under Me" and "Schoolin 'Life".
