James Blake and Diplo feature on Beyoncé's new album

Beyoncé loves a surprise, doesn't she? After spontaneously releasing a self-titled album in 2013, the singer's dropped another LP out of the blue.

A visual album called 'Lemonade', it features James Blake on two tracks, one as a writer ('Pray You Catch Me') and another as a feature ('Forward'), with Diplo also chipping in with production.

Kendrick Lamar, Jack White and Vampire Weekend's Ezra Koenig are other collaborators, and it's now available on Tidal having originally premiered on TV station HBO on Saturday.
