This most-streamed female artist for the third year in a row had a smash hit with her Eminem collaboration, The Monster, last year. The song has been streamed over 200 million times on Spotify. With this service, users don’t download content, rather it is seamlessly delivered to them via the Internet. Katy Perry, Beyonce, Lana Del Rey and Lady Gaga were next up on the list." & @CRLF
