The series' fourth and final entry of 2018, Now That's What I Call Music! 68 includes 21 mostly midtempo pop, rap, and EDM tracks, all from 2018, including hits from Post Malone ("Better Now"), Ariana Grande ("God Is a Woman"), and the Chainsmokers ("Side Effects" featuring Emily Warren). Also represented are Imagine Dragons, Ella Mai, and Lauren Daigle, whose "You Say" topped the Christian Songs chart. Deep into the track list are a handful of songs that didn't hit the Hot 100, or at least hadn't by the time of the collection's release, including "Can't Stop Rollin'" by soul-rock band Vintage Trouble, "You're Somebody Else" by indie folk-pop duo Flora Cash, and "El Dorado," the official debut single from pop singer Shaylen. ~ Marcy Donelson
