Ghostbusters, sometimes referred to as the "Ghostbusters theme song", is a song written and performed by Ray Parker, Jr.. It has been used in just about every incarnation of the Ghostbusters franchise, from the first movie and onward.
After test screenings in early 1984, Ivan Reitman wanted song about 20 seconds in length at the beginning of the movie when Peter and Ray enter the New York City Public Library.  Reitman simply wanted a song that said "Ghostbusters" in it. Columbia Pictures spent a lot of money to have different musicians write songs to be considered as the main song for the Ghostbusters movie, but could not find one that they liked. Reitman didn't like any songs he got back either. They did use a song by Pat Thrall and Glenn Hughes for the film's teaser trailer, but chose not to use it for the movie. Ray Parker, Jr.'s old music industry friend Gary LeMel, had suggested that he try his hand at writing a song for the film. In place of a music supervisor on the movie, the head of the music department at Columbia Pictures introduced R&B artist Ray Parker Jr. to Reitman and co-producer Joe Medjuck. Producer Clive Davis who ran Arista at the time didn't want Parker singing a song about ghosts. Parker's forte was songs about romancing women. Davis took a lot of convincing.
The catch was that the song was needed in two days since the film due to be released soon.  The movie producers wanted a song people could sing along with - without "too much meaning". The hardest task for Ray was coming up with a rhyme for "Ghostbusters".  Parker recorded a minute of so on a cassette and gave it to Reitman. A short time later, Reitman called Parker at 3:30 or 4:30 in the morning praising the song. Reitman pushed for the 20 second intro song to be made into a single backed by a music video.
These are official recordings of the song by Ray Parker Jr. that have been released to the public by Arista and Sony. Runtimes listed are the official runtimes as listed on the record singles, images of most can be found in the Gallery section below. Some sources list a runtime that is a second or two different, so runtimes are listed as a guide and not meant to be 100% exact.
It should also be noted that a few of the 7"/45-rpm records list a 3:45 "regular" version and a 4:07 "Instrumental" version, but that may be an error. No other versions of the "regular" and "instrumental" versions are so short. Maybe the two songs were sped-up for jukebox play. Until it can be proved if that's the case, or not, they are not being listed below but will be noted in this paragraph.
- Album Version/7" Version/Short Version (4:04) - available on the Soundtrack album and just about every released single.
- Instrumental Version (4:48) - available on the Soundtrack album and the 30th anniversary record single.
- Extended Version/12" Single Remix (6:08) - available on several record singles, Ray Parker Jr.'s "Chartbusters" album, and the 2006 reissue of the soundtrack album.
- Searchin' For The Spirit Remix (5:19) - available on the Searchin' For The Spirit/Dub Instrumental Version record single. 
- Dub Version (5:35) - available on the 30th Anniversary record single.

- 2009 Re-Recording (3:42) - available on the Atari Ghostbusters: Sanctum of Slime website for a limited time in 2011.  Do note that the original Atari MP3 has ID3 data that gives a "2007" date, which either means that this version was recorded two years before it debuted to the public, or the 2007 date could simply be a mistake. )
Like many movie soundtrack videos, it uses both a recreation of the concept of the movie and actual clips from the movie. However, its an interesting music video as many actors (many of which didn't appear in the Ghostbusters film) show up singing the song in little bit cameos. The lead is singer Ray Parker Jr. and lead actress is Cindy Harrell.
The music video was recorded at A&M Studios in Hollywood without a proper director. Ivan Reitman sort of just took over directing it. The set of the haunted house was still being constructed up to when filming started. An old shooting technique of painting on glass then shooting through the house created the drawn look. After the painter started, Reitman set up the camera and the video was shot. Parker was a little concerned about looking silly as a singing ghost but Reitman ran with the concept and recruited celebrity cameos. Some cameos were favors that were called in. Teri Garr just filmed "Tootsie" with Bill Murray. Reitman, Medjuck and a small crew went to where "Brewster's Millions" was shooting, made their way past security, and had John Candy shoot his cameo between takes. While filming "No Small Affair" at Burbank Studios, George Wendt filmed his cameo for free during a lunch break. He later got in trouble with the Screen Actors Guild for that arrangement but was merely told not to do so again.
For the ending of the music video, the crew blocked off Times Square at the same time the press junket for the movie took place in New York. The scene was not planned and essentially shot for a day with no permit. On a Friday afternoon at 1 pm, Parker filmed with Bill Murray, Dan Aykroyd, Harold Ramis, and Ernie Hudson in character as his backup singers. Murray did an impromptu breakdancing routine. Parker improvised and helped spin Murray around. Since the actors in the music video weren't paid for their appearance, the video could not appear in home video releases for the film.

- The music video is seen and heard on a television at the beginning of Ray Parker, Jr.'s "Girls Are More Fun" music video. Ray tries to convince a woman, played by Irene Cara, that he's really Ray Parker Jr. She sarcastically rebuffs him by saying, "Yeah, and I'm Irene Cara,", and then walks away. At this point, Ray sees the "Ghostbusters" music video on a television and comments, "Hey! That's me!". Irene Cara also made a cameo appearance in the "Ghostbusters" music video.

The song was number one on Billboard's Hot 100.
Parker's "Ghostbusters" and Michael Jackson's "Thriller" were one of the first music videos starring a black music artist to appear on MTV.
The song is responsible for adding the catchphrases "Who you gonna call?" and "I ain't afraid of no ghost" into the pop culture lexicon.
The song has been repeatedly referenced in assorted forms of media.
- The Huey Lewis Controversy (see below) was directly referenced in a portion of the Webcomic The Adventures of Dr. McNinja, where the titular character is humming the song when suddenly a nearby person screams "I WANT A NEEEW DRUG", and then says that he thought Dr. McNinja "was humming Huey Luis".
Huey Lewis ControversyEdit
Huey Lewis filed a lawsuit claiming the song sounded too much like Huey Lewis and the News' "I Want a New Drug." Others found the score's synthesizer notes (that were held for several seconds) akin to the chord struck in Gary Numan's "Cars". The lawsuit was settled out of court and the outcome was kept private.
