How has Britney Spears changed music?

YES! Its no doubt that she changed her style of music, with NEW pop star singers such as Katy Perry, Ke$ha, and Lady Gaga, they have all changed the style of Pop Music. Britney Spears was known for singing in either a red tight suit, or diamon dress, or even a biker girls outfit, but Fashion is now an important part in music videos, so is the type of music that goes with it. Britney Spears is going for a new Techno and Electric type of music, but Britney always has new plans for her next big thing, so don't feel like her "Old" style of pop music is gone just yet.
