In 1992, Orlando talent manager Lou Pearlman placed a classified ad seeking singers, and a year later Nick Carter, Howie Dorough, AJ McLean, and cousins Brian Littrell and Kevin Richardson had formed around it. They spent the next few years insisting they were something other than what that ad implied: a boy band built for dancing. Fighting comparisons to New Kids on the Block's lip-sync scandal, they sang a cappella at every chance they got, staking their identity on the vocal-group tradition rather than the choreography. In 1995 they carried that conviction to Stockholm, cutting their self-titled debut at Cheiron Studios under Denniz PoP and a young staff producer named Max Martin. What emerged from that room — American R&B harmony welded to Scandinavian pop engineering — made them the best-selling boy band in history.
When Pearlman wrote his 1992 notice, he wasn't shopping for a vocal group so much as a substitute: he wanted singers with "the New Kids on the Block look with a Boyz II Men sound," aiming, in the band's own account, for something close to a white version of the Philadelphia quartet whose "End of the Road" and "Motownphilly" had just redrawn what an R&B group could be. The Backstreet Boys spent their early years chasing that sound on purpose, learning Boyz II Men songs in rehearsal before they had hits of their own to sing.
listen forReviewing "I'll Never Break Your Heart" in 1996, People's Chuck Arnold wrote that the Backstreet Boys gave their "smoothest Boyz II Men impression" on the ballad, and the comparison holds up side by side. "End of the Road" trades its lead line between voices rather than parking it behind one singer; "I'll Never Break Your Heart" does the same, stacking Littrell, Carter, and McLean into one blended vocal surface before a single voice steps forward for the hook.
Working on 2009's This Is Us, the group went looking for what had shaped them as teenagers. "Jodeci, Boys II Men, Shai, New Edition… we had to go back and remember our influences and what taught us in the years when we were developing into a band," Nick Carter told Rolling Stone. Jodeci topped that list for a reason: their gospel-trained, ad-lib-heavy delivery on early-1990s hits like "Stay" gave the group a template for making a boy-band ballad sound like it actually hurt to sing.
listen for"Stay" rides on K-Ci Hailey's raspy, half-improvised vocal runs stacked over a slow, new-jack-swing groove, the ad-libs carrying as much feeling as the melody itself. "I Want It That Way" borrows that architecture: each of the five members takes a turn on lead, the mix quietly shifting whose line is dominant, before the whole arrangement steps up a full key for the final chorus — a swing for the same ache Jodeci spent an entire song building.
Of the three names, Shai is the one most listeners need introduced. Formed by members of Howard University's gospel choir, the group broke through in 1992 with "If I Ever Fall in Love," a hit carried almost entirely by a cappella harmony. Littrell made sure Shai got its due: "We were fans of New Kids, but were we really modeled after them? No. We looked at ourselves as Shai, Jodeci, and Boyz II Men, the true vocal groups. That's who we listened to and who we really wanted to be like," he told Entertainment Weekly in 2011.
listen for"If I Ever Fall in Love" opens on four unaccompanied voices stating the melody cold, a cappella as a statement of purpose before a single instrument enters. "Quit Playing Games (with My Heart)" never goes fully bare, but its chorus works toward the same idea: Littrell and Richardson's backing parts stack so tightly under Carter's lead that reviewers singled out the harmonies themselves, not the guitar riff underneath, as the song's actual hook.
