The group, who have sold over 76 million albums in their 12-year career, attributed their past success to producing contemporary-sounding records.
"We always try to set the bar as high as possible," Howie Dorough told Billboard. "We've always been a pop R&B group. We focus our songs around good melodies and group harmonies, and hopefully that will have a lot of staying power."
Despite no longer selling as many records as they did in their heyday, Dorough claimed that the boyband are still confident that they can appeal to new audiences.
"I think every artist who wants to be around for a long time and have staying power has to go through that transition," he said. "Some records are going to be bigger than others. You're always going to be compared to your biggest record. All you can do as an artist is just strive to make the best record you can and ride the rollercoaster as it goes up and down.
"I think, overall, we're gonna be a group that's here for a long time. As long as people want us and our fans want us, then hopefully we can ride the wave - like I say, the rollercoaster - up and down, and be standing at the very end."
Backstreet Boys teamed up with producers including Max Martin, T-Pain, RedOne, Soulshock & Karlin, Jim Jonsin and Claude Kelly for their new album This Is Us, which is released on October 5.
