Surprise! While the world was busy freaking out about Taylor Swift's new album [1], Reputation, Eminem [2] pulled a fast one. The world-renowned rapper unexpectedly dropped a new single called "Walk on Water" on Friday, and it features the unmistakable voice of Beyoncé Knowles [3]. Eminem has been popping up in headlines quite a bit over the past few weeks and in the best way. Not only is there an imminent new album [4] on the horizon, but he also recently donated to hurricane relief efforts [5] and even dropped an epic takedown of Donald Trump [6]. A Beyoncé collab is just the icing on the cake.
