Ray Parker Junior

Ray Erskine Parker, Jr. (born May 1, 1954) is an American guitarist, songwriter, producer and recording artist. Parker is known for writing and performing the theme song to the motion picture Ghostbusters, for his solo hits, and performing with his band Raydio as well as the late Barry White.

Ghostbusters theme song controversy
«Ghostbusters» was the title track of the Gold-selling soundtrack of the hit movie Ghostbusters, starring Bill Murray, Dan Aykroyd, Harold Ramis and Ernie Hudson. The single was at #1 for three weeks on Billboard’s Hot 100 chart, and at #1 for two weeks on its Black Singles chart. The song was also nominated for an Academy Award for Best Original Song in 1984 but lost to Stevie Wonder’s «I Just Called to Say I Love You» from The Woman in Red.
Parker was accused of plagiarizing the melody from Huey Lewis and the News song «I Want a New Drug», released only six months after Lewis’ hit reached #6 in the Billboard Hot 100. This ended with Lewis suing Parker, and the pair settled out of court in 1985. Nonetheless, Parker’s success continued as the song secured him a 1984 Grammy Award for Best Pop Instrumental Performance.
They returned to court once again in 2001, as Parker sued Lewis for breaching a confidentiality agreement forming part of their original out of court settlement which prohibited either side from speaking about it publicly. Lewis had implied in a VH1 Behind The Music special that Parker had paid a financial settlement as part of the original agreement.
Both «Ghostbusters» and «I Want a New Drug» have been accused of lifting their bass lines from the 1979 M song «Pop Muzik.»
