Beyond her stellar hits, Kylie Minogue pushes the boundaries of the dancefloor. Back in 1999, she traded risqué verses with The Pet Shop Boys on the string-soaked “In Denial”; later, Giorgio Moroder harnessed her bubbly vocals against the ecstatic oscillations of “Right Here, Right Now.” The chart-topper has even gotten adventurous with sharp electro-pop and percussive Eastern twang, smashing preconceptions while keeping bodies moving.
