There are also several differences between the songs from the international debut album and both 1997 and 1998 pressings of the Backstreet Boys compilation. The 1998 pressing contains the single mixes of "Quit Playing Games" and "As Long as You Love Me". For the single version of "Quit Playing Games", the second verse was re-recorded to feature Nick Carter, replacing Brian Littrell's verse from the original version. The single version of "As Long as You Love Me" uses different instrumentation, arrangement and mixing and was released on the 1998 pressing of the album and on The Hits – Chapter One (2001). The Backstreet's Back album contains the original version of "Everybody (Backstreet's Back)", while the 1998 pressings of the Backstreet Boys compilation use an extended version.
