Vanity Fair editors have crowned The Shake It Off hitmaker number one for her career achievements and the influence she has over the music industry, shown when she pulled her catalogue from music streaming service Spotify and then forced Apple bosses to rethink a decision not to pay artists during a trial of their new music service.

Star Trek and Star Wars director J.J. Abrams also makes the list at number seven, while fellow filmmaker Lee Daniels places number 10 thanks to his hit series Empire.

Kanye West and Kim Kardashian, Bradley Cooper and Jay Z and Beyonce, are also included on the list at numbers 12, 18 and 21, respectively.
