Ray Erskine Parker Jr. (born May 1, 1954) is an American guitarist, singer-songwriter,  record producer, and actor, best known for writing and performing the theme song to the movie "Ghostbusters", for his solo music, and for performing with his band, Raydio, and with Barry White.
The Ghostbusters movie's theme song is well known and Ray Erskine Parker Jr. performed it with his band, Raydio.
Given the context, the Ghostbusters theme song is well known and why Ray Parker Jr. is well known, but he may have performed it solo OR with his band. I think the system probably just found the key words and didn't pick up on context.
