Anthology: Set the World Afire is the third greatest hits album by Megadeth. It was released on September 30, 2008, by Capitol Records. It is a 2-disc set with additional songs not offered in previous compilations including demos, live performances and unreleased tracks. The album was apparently supposed to include the track "Sleepwalker" from the previous year's release, United Abominations, but this was replaced by "Foreclosure of a Dream" from Countdown to Extinction instead, resulting in that track being the exception on the otherwise chronological tracklisting of the album. Anthology: Set the World Afire sold about 2600 copies in the U.S. in its first week.
