Lest We Forget: The Best Of

Lest We Forget: The Best Of is a greatest hits album by American rock band Marilyn Manson. It was released on September 28, 2004, by Interscope Records. The album was conceived by the band's eponymous vocalist as a "farewell compilation", and was originally going to feature a duet with Shirley Manson of Garbage. Upon its completion, neither singer was satisfied with the duet, and it remains unreleased. Instead, the band recorded a cover of Depeche Mode's "Personal Jesus" (1989), which became the only new track on the album and was released as a single. The deluxe version of the album included a bonus DVD containing sixteen music videos, one of which was the previously unreleased uncensored version of the music video for "Saint" (2004).

Lest We Forget: The Best Of received mostly positive reviews from music critics, several of whom complimented its track listing. The compilation's commercial performance exceeded expectations in the United States, where it sold over 78,000 copies in its first week of release and had sold over a million copies as of late 2010. It was also successful internationally, peaking within the top 10 of national record charts in Austria, Germany, Spain, Sweden, Switzerland and the United Kingdom. The band promoted the album with their "Against All Gods Tour".
