Despite receiving mixed reviews from critics,^[12] the album was a commercial success, peaking at number two on the Billboard 200 and being certified platinum by the RIAA.^[1][4] It spawned four singles, including the international hit "Beverly Hills", which became the band's first top ten hit on the US Billboard Hot 100 and the top-selling download of 2005.^[13][14]

The band's third self-titled studio album – commonly referred to as The Red Album – was released in June 2008 as their sixth studio album.
