"100 Little Curses" is the first single by Street Sweeper Social Club, from their self-titled album. The song made its debut on the band's Myspace page. The song contains a sing-a-long chorus, arena rock style, with a digitally edited voice then speaking the words "100 Little Curses." It was released as a digital download on April 27, 2009 before the album was released. Tom Morello performs the song on his 'Arm the Homeless' guitar, in standard tuning. The song made its live debut in mid-2008, during The Nightwatchman's Fabled City tour, when opener Boots Riley would test this one Street Sweeper song. It later became a staple in the band's set in 2009, when Street Sweeper Social Club opened for Nine Inch Nails and Jane's Addiction on the NIN|JA 2009 tour.
The music video was first aired on Facebook on June 18, 2009, and features actor Breckin Meyer who's also the live drummer of Tom Morello's solo band.
