"Oh My God" is a song by Guns N' Roses released in 1999 on the soundtrack to the film End of Days. The song was sent to radio stations in November 1999 as a promo for the soundtrack and the band. Despite being the band's first recorded release in almost five years, it was never issued as a stand-alone single for public retail. The song was written as the band was recording music for Chinese Democracy.
