The soundtrack for Ghostbusters II. It contains an Elton John song that was composed for the film but never used. Most of the album's songs are played only as the closing credits roll, and only Bobby Brown's "On Our Own" has a key role in the movie. These days songs on a soundtrack are often "source" music: stuff that plays in the background as characters talk in a diner, or on the radio of a passing car. Most of all it has the Ray Parker Jr. Hit.
