Now That's What I Call Music! delivers its second collection of 2015 with the 91st edition of the long-running series. At a hefty 44 tracks, this double disc has plenty to offer in the way of pop chart-toppers and rising stars alike. Feel-good singles like OMI's "Cheerleader," Aston Merrygold's "Get Stupid," and John Newman's "Come and Get It" give the compilation a buoyant, carefree feeling while brooding singer/songwriters like James Bay and Hozier add a flash of darkness. ~ Timothy Monger
