Back when Alanis Morissette covered Fergie's "My Humps," [1] I thought it was funny. Now Australian pop star Sia has done a cover of Britney's "Gimme More" [2], which comes to us via Underwire [3], and it actually makes me like the song a little more. Slowed down and made into a sweeter tune, Sia's song is less nightclub and more coffee shop. What do you think of this "Gimme More" — love it or leave it?
