"You Could Be Mine" was Guns N' Roses' seventh single off their 1991 album Use Your Illusion II. It was also the theme for Terminator 2: Judgement Day.
It wasn't originally supposed to be the theme to the movie, but there were some pretty obvious references to the band in the movie from John Connor's friend's L.A. Guns t-shirt and T-800 taking a gun from a box of roses that it made sense for GNR to do the music. Arnold Schwarzenegger had the band over to his house to negotiate the deal.
"You Could Be Mine" ended up being a pretty big hit for the band reaching #26 on the Billboard Hot 100 and #2 on the Mainstream Rock Tracks chart.
