Query: not her best form!

certainly this is not her best album, but a compilation instead, is she trying to get away from all the rumors that she is not having any breakthrough...and she have to stood as low as to come out with a compilation that have her previouc hits together with the new songs, so that she can make her not so good songs look good...a really brilliant move...in fact scheming enough !
