No Doubt went into hiatus in April 2003 after the release of four singles from their fifth studio album, Rock Steady, allowing the four members to spend time with loved ones.

The album was commercially successful, selling three million copies worldwide and being certified platinum by the Recording Industry Association of America (RIAA).

[1][2] In April 2003, No Doubt went into hiatus to take a break to spend time with their families before starting to compile The Singles 1992–2003, which would feature the band's greatest hits from their previous albums.

[3] The main reason to go into hiatus was that, in early 2003,[4] their lead singer Gwen Stefani started work on her 1980s-inspired music side project, under which she released two solo albums—Love.

"Girls Get the Bass in the Back", a remix of "Hey Baby", and a live acoustic version of "Underneath It All" were included as bonus tracks on international pressings of the album.

[7][8] The song was nominated for Best Pop Performance by a Duo or Group with Vocals at the 47th Grammy Awards, but lost out to Los Lonely Boys' "Heaven".

[9] Stuart Price (also known as Jacques Lu Cont), the song's programmer, created the Thin White Duke mix of "It's My Life", which won the award for Best Remixed Recording, Non-Classical.

Mike McGuirk of Rhapsody described the album as "a real joy for anyone who has a taste for Gwen Stefani's yearning vocals and her band's uncanny ability to mix ska, teen pop and hip-hop.

"[15] Stephen Thomas Erlewine of AllMusic called the album a "stellar collection", concluding that it is "the kind of compilation that satisfies fans of all stripes and converts skeptics.

"[11] Anthony Thornton of NME stated, "Despite being an album packed with as much drama as the band themselves have suffered, it'll be the pop anthems you come back for and fortunately there's enough here to keep even the soap addicts happy.

[17] The album was certified double platinum by the Recording Industry Association of America (RIAA) on July 21, 2004,[18] and had sold 2,474,000 copies in the United States.

[19] In Canada, the album was certified double platinum on June 13, 2005 by the Canadian Recording Industry Association (CRIA), denoting sales of over 200,000 copies.
