Madonna was a trailblazer in so many ways during her still-going career. She's pushed the envelope in the music industry in countless ways from singing about taboo themes such as abortion and homosexuality to putting it all out there—literally—in the pages of her Sexbook.
Today, she's recognized as the best-selling female artist of all time. Musicians today like Miley Cyrus and Beyoncé, among others wouldn't be as far along as they are without her influence. Could anyone else have pulled off a cone bra? We think not.
