Rihanna, Beyonce rule women on Spotify

Beyonce sang that girls "run the world" but she is not alone in ruling Spotify, where Rihanna is giving her a strong challenge. The leading streaming service released a list of the most popular female artists for International Women's Day and found that Rihanna was the most listened to globally. The Barbados-born singer's 2012 hit "Diamonds" has been streamed nearly 240 million times and "FourFiveSeconds," her collaboration with Paul McCartney and Kanye West, has more than 282 million listens.
