Thanks to their teen-dream charm, soaring harmonies and ability to stay on the cusp of millennial pop trends, *NSYNC were boy-band royalty in the late ‘90s and early ‘00s. Stomping tracks like the kiss-off “Bye Bye Bye” and the glitchy boast “Pop” were as notable for their forward-thinking touches as they were for their club readiness, while ballads like the sparse “Gone” and the gently adoring “God Must Have Spent a Little More Time On You” showed off the quintet’s swoon-worthy side.
