A definitive hits arsenal from a pop phenomena. The genesis of ‘90s UK pin-up pop—and Gary Barlow’s own songwriting confidence—can be charted through this retrospective. Opening on the band’s stonking (first) farewell "Never Forget", it tracks back, out of order, through the canny ‘70s do-overs ("Relight My Fire", "How Deep Is Your Love"), swoonsome platinum hits like the exotic "Pray", and epic piano-stool harmonies of "A Million Love Songs".
