Which song by Guns N' Roses contains the lyric 'I used to love her but I had to kill her'?

The Guns N' Roses song containing the lyric “I used to love her but I had to kill her” is “Used to Love Her.” It appears on the band's 1988 album G N' R Lies.

The song was written as a darkly comic roots-rock number rather than a literal confession. Izzy Stradlin explained that he was parodying a radio song about a man complaining about a woman, rewriting it with an absurdly violent ending. The deliberately blunt lyric helped make the track one of Guns N' Roses' most memorable early songs.

Despite its disturbing wording, the song is commonly understood as satire. It is often mistakenly treated as autobiographical or connected directly to Axl Rose's personal relationships, but the band's explanation emphasizes its joke-song origin.

“Used to Love Her” was released in 1988 and was also used as a B-side on some editions of the “Paradise City” single. Its acoustic, country-leaning arrangement differs noticeably from the band's heavier hard-rock anthems.
