Four 1988 acoustic songs are listed on G N’ R Lies. They are the album’s final four tracks: “Patience,” “Used to Love Her,” “You’re Crazy,” and “One in a Million.”
G N’ R Lies was released on November 29, 1988, and combines two different releases. Its first four songs come from the 1986 EP Live ?!*@ Like a Suicide, while the closing four were newly recorded acoustic-based performances. That structure is why the album is sometimes described as half live-style hard rock and half stripped-down acoustic material.
The acoustic songs were recorded in only a few studio sessions, creating a notably immediate contrast with the band’s heavier debut album, Appetite for Destruction. “You’re Crazy” is especially easy to miscount because a faster electric version had already appeared on Appetite for Destruction.
G N’ R Lies was Guns N’ Roses’ second studio album and became a major commercial success, reaching No. 2 on the Billboard 200. The answer is four because the question refers to the acoustic closing section, not every song associated with acoustic guitars across the band’s catalog.
