Yesterday (feat. Bebe Rexha)
Even for cosmopolitan dance pop, the guest list here is staggering. Nicki Minaj, Sia, MAGIC!, Elliphant, the guy from OneRepublic, and Ladysmith Black Mambazo, and that barely brings us halfway through the album. By now, the French DJ's M.O. is tried and true -- emoting vocalists, block-rocking beats and a bit of the old wiggle-squiggle. Too bad the beats often take a back seat to Eurocheese strings and minor key intros, because Guetta's best when he's most shameless. Seek out the spaghetti western guitars of "Lovers on the Sun" and the swaggering Nicki-aided Afrojack number "Hey Mama."
