在即将迈入千禧年的前夕，Backstreet Boys在1999年夏天发行了「千禧年（Millennium）」专辑，果不出所料，专辑一推出就于首周夺得全美专辑榜冠军，并且首周销售量就突破一百万大关，使得Backstreet Boys成为Billboard杂志采用SoundScan系统以来第一组首周专辑销售量破百万的艺人。专辑里的几首单曲：""I Want It That Way"、"Larger Than Life"、"Show Me the Meaning of Being Lonely"以及"The One"因为居高不下的之声播放率而相继打入全美热门单曲榜，专辑本身也在发行后没多久就创下单在美国就有一千两百多万张的傲人销售成绩
