a separate CD on October 12, 2004. The Videos 1992–2003 was released on a separate DVD on May 4, 2004. Music Boom Box compiles four albums: Everything in Time, The Singles 1992–2003, The Videos 1992–2003, and Live in the Tragic Kingdom. The Singles 1992–2003 is a greatest hits collection of No Doubt's singles, containing tracks from four of their five studio albums: No Doubt, Tragic Kingdom, Return of Saturn, and Rock Steady. Tracks from No Doubt's second album, The Beacon Street Collection, were not included because the album was produced and released independently by the band. The Videos 1992–2003 is a DVD containing No Doubt's music videos, including those of all the tracks on The Singles 1992–2003 as well as a video of the band's cover of "Oi to the World!", a song originally by Californian punk rock band The Vandals from their album of the same name. Everything in Time is a CD collection of B-sides, rare songs, and remixes. Live in the Tragic Kingdom is a DVD filmed at one of the concerts in No Doubt's Tragic Kingdom tour and contains performances of the seven songs released as singles from Tragic Kingdom, along with other tracks from the album and cover versions of songs by other bands. Boom Box spans mostly No Doubt's later musical style. The two greatest hits discs, The Singles 1992–2003 and The Videos 1992–2003, take 13 of their 15 or 16 tracks from Tragic Kingdom, Return of Saturn and Rock Steady. Their earlier musical style, in which the songs were written by keyboard player Eric Stefani, who left the band before Tragic Kingdom was recorded, is represented by only one song—"Trapped in a Box" from No Doubt. The band's musical style changed later when Gwen Stefani started writing the songs; the tracks on Tragic Kingdom, which are heavily represented on Boom Box, are built on the themes of Gwen Stefani's femininity and the breakup of her relationship with fellow band member Tony Kanal. The B-sides and rare songs on Everything in Time were mainly recorded in the sessions for the band's fourth album, Return of Saturn, but two of the three remixes were of the song "Rock Steady", from No Doubt's album, Rock Steady. Boom Box was given a Parental Advisory: Explicit Content sticker in the United States because of the content in Live in the Tragic Kingdom, which also received the sticker upon
