Featuring artists like One Direction, the Lumineers, and Rihanna, Now That's What I Call Music!, Vol. 84 skims the charts for the cream of the pop crop. A snapshot of what's happening in pop music at any given time, this two-disc sets captures the U.K. radio waves circa March of 2013, and even though these songs are very much a part of a certain time and place, chart-topping covers of tracks like "One Way or Another" and "He Ain't Heavy, He's My Brother" show that some things never change. ~ Gregory Heaney
