What is the only Appetite for Destruction song to feature a synthesizer?

“Paradise City” is the only Appetite for Destruction song to feature a synthesizer.

The song appears on Guns N' Roses' 1987 debut album and was written by Axl Rose, Slash, Izzy Stradlin, Duff McKagan and Steven Adler. Its synthesizer part is credited to Rose, whose keyboard contribution adds a distinctive texture to an otherwise guitar-driven hard-rock recording.

“Paradise City” was released as a single on November 30, 1988, after “Welcome to the Jungle” and “Sweet Child o' Mine.” It became the band's third US top-10 single from the album, reaching number five on the Billboard Hot 100, and it also reached number six in the United Kingdom.

The track is sometimes remembered mainly for its famous “Take me down to the paradise city” chorus and extended guitar work, which can make the keyboard contribution easy to overlook. In live performances, it has also commonly served as the band's closing encore.
