Our list of the Madonna's 50 greatest songs is a fitting tribute to the 2008 Rock and Roll Hall of Fame inductee, whose gift to songwriting is matched only by her skill for finding the right partners to unlock her creativity: Prince, William Orbit, Diplo, Justin Timberlake and more. The stories behind Madonna's songs reveal the evolution of the only artist in the world who's equally at home in the club, in the church and on the catwalk; there are psychosexual dramas, disco reveries, tear-jerking ballads and pop songs that unite the globe – all by an artist who has never risked making the same album twice. "I don't think about my old stuff," she told Rolling Stone in 2015. "I just move forward." Madonna is as restless as she is relentlessly imaginative – and we just can't look away.
