Calvin Harris is the biggest DJ in the world. This is true in terms of dollars (he's Earth's highest-paid party-rocker, by an even larger margin than last year) and human bodies (he appeared to draw the most massive crowd at Coachella this year). "Summer," a song he sung himself, hit the US top 10 and was a legitimate Song Of The Summer contender. Now that we're into autumn, his John Newman collaboration "Blame" is the #1 song on Spotify. And with this week's announcement of a new album featuring everyone from Ellie Goulding to Big Sean to Gwen Stefani to Haim to Tinashe, Harris seems poised to continue his dominance. Judging from the smash success of those singles and the star-studded look of the tracklist -- a reprise of the approach that made 2012's 18 Months such a smash -- the new Motion is all but predestined to keep Harris on top of the world.
