At the 2001 California Music Awards, Green Day won all eight awards that they were nominated for. They won the awards for Outstanding Album (Warning:), Outstanding Punk Rock/Ska Album (Warning:), Outstanding Group, Outstanding Male Vocalist, Outstanding Bassist, Outstanding Drummer, Outstanding Songwriter and Outstanding Artist.[22]
The release of a Greatest Hits compilation, International Superhits!, and the token complementary assemblage of B-sides, Shenanigans, only fueled the theory that Green Day's career was on the rocks. International Superhits and its companion collection of music videos, titled International Supervideos! sold reasonably well, going platinum in the U.S. Shenanigans sported the band's b-sides, including "Espionage" which was featured in Austin Powers: The Spy Who Shagged Me and was nominated for a Grammy for Best Rock Instrumental Performance. "Ha Ha You're Dead," recorded specifically for Shenanigans, is seen as the highlight of the album.
In 2002, Green Day co-headlined the Pop Disaster Tour with Blink-182. The tour helped to resurrect some of the band's popularity, and earned the group many positive concert reviews. The band decided to take some more time off after the Pop Disaster Tour closed, to spend more time with their families.
