“Now the party don’t start ’til I walk in,” drawls Kesha Sebert on indomitable electro-pop calling card “Tik Tok”. Hard to argue with that logic in the face of Animal’s relentless floor-filling euphoria. Whether hurtling from the snapping attitude of “Blah Blah Blah” to the whistle-along brio of “Dinosaur”, Kesha brings the melodic best out of her Swedish production hitsmiths (Dr Luke and Max Martin) while making an indelible—and slyly empowering—first impression.
