In most markets, the album contains 18 songs: 16 of their most successful and popular singles, and two new songs. The 17th track is a cover version of the Skids' "The Saints Are Coming", recorded with Green Day to benefit Hurricane Katrina charities. The 18th and closing track was a new song entitled "Window in the Skies". In some markets such as the United Kingdom, an extra song, "I Will Follow", was included as the opening track. A DVD compilation of music videos from throughout the group's career entitled U218 Videos was released concurrent to U218 Singles.
