Madonna’s musical career began in the 1980s. Since then, the singer has succeeded not only in fulfilling her potential as a vocalist and songwriter, and making a name for herself as a dancer, actress, producer, scriptwriter and director, but has earned the title "Queen of Pop". Madonna is the most commercially successful female performer ever, with the highest number of records sold. In 2012, Madonna’s twelfth studio album was released.
