No Doubt released the less popular Return of Saturn in 2000, which expands upon the New Wave influences of Tragic Kingdom. Most of the lyrical content focuses on Gwen Stefani's often rocky relationship with then-Bush frontman Gavin Rossdale and her overall insecurities, including indecision on settling down and having a child. The band's 2001 album, Rock Steady, explores more reggae and dancehall sounds while maintaining the band's New Wave influences, generally receiving positive reviews. The album generated career-highest singles chart positions in the United States, and "Hey Baby" and "Underneath It All" received Grammy Awards. A greatest hits collection, The Singles 1992–2003, which includes a cover of Talk Talk's "It's My Life", was released in 2003 to moderate sales. The other members of No Doubt have begun work on a new album and plan to complete it after Stefani's tour is finished.
