'Love is a Battlefield' was a 1985 hit for which singer?

"Love Is a Battlefield" is a million-selling, gold hit performed by Pat Benatar, and written by Holly Knight and Mike Chapman. It was released in September 1983 as a single from Benatar's live album Live from Earth, though the song itself was a studio recording. The song was ranked at number 30 in VH1's list of the 100 Greatest Songs of the 1980s.

Holly Knight and Mike Chapman wrote this song for Pat Benatar initially as a ballad with a beautiful melody and moving chord changes. After some exploration with drum machines and the band, Neil Giraldo decided to make this an uptempo song. The single was Benatar's second American million seller and is tied with "We Belong" as her highest charting single in the United States. It topped Billboard's Mainstream Rock Tracks chart for four weeks and peaked at #5 on the Billboard Hot 100 in December 1983.
