I remember a similar case. Representatives for Huey Lewis and the News claimed Ray Parker Jr. sole a part of “I want a New Drug” and used it in “Ghostbusters”. Ironically a guitar riff from “Purple Haze” was heard in the Huey Lewis tune.
Not much, though. Only the bass line, main guitar riff, song structure, and bridge. </sarc>
Way back when, they settled out of court. Then, ironically, Parker sued Lewis when he talked about the settlement payment on TV, supposedly breaking a confidentiality agreement.
