Question: When did The Terminator's soundtrack come out?
About the article "The Terminator", section "Post-production".

Candidate passages:
After production finished on "The Terminator", some post-production shots were needed.
These included scenes showing the Terminator outside Sarah Connor's apartment, Reese being zipped into a body bag, and the Terminator's head being crushed in a press.
The film's soundtrack was synthesizer music composed by Brad Fiedel.
Fiedel described the film's music as being about "a mechanical man and his heartbeat".
Almost all the music in the film was performed live.
"The Terminator"s theme is played over the opening credits and is played in various points in the film in sped up versions: a slowed down version when Reese dies, and a piano version during the love scene.
Fiedel created music for when Reese and Connor escape from the police station that would be appropriate for a "heroic moment".
Cameron turned down this theme, as he believed it would lose the audience's excitement.
The soundtrack to the film was released in 1984.
In November 1976, Pickwick Records reissued the soundtrack album with a new cover showing a 1970s-era image of Presley.
The running order of the tracks was altered and three songs from the original album were omitted —"Chesay", "Look Out Broadway", and "Everybody Come Aboard".
The front cover does not indicate that this is a reissued soundtrack album, and it was the only soundtrack to be reissued in this way.
It did not chart on the Billboard 200.
This oddity remained in print for several years and when, following Presley's death in August 1977, RCA reissued all of his albums, the agreement between RCA and Pickwick prohibited RCA from reissuing the original, complete soundtrack album in the US for several years.
The original "Frankie and Johnny" soundtrack album was reissued in Canada and elsewhere however.
Not until 2010 would the complete original "Frankie and Johnny" soundtrack be widely available in the United States. 
In the novel, when the T-X's plasma cannon is damaged, she modifies it into a weaker, yet effective version of the weapon.
In the film, her onboard computer automatically switches the weapon to an IAD-ChemTech (flamethrower).
The novel describes the T-850's skin as being made of duroplast, a form of pliant plastic, while the films continually describe the Terminator's skin as being genuine, cloned, living human tissue. 
Come Back Around featured on the soundtrack to the gross-out comedy American Wedding.
It plays very quietly on the radio during the sports shop scene.
