We have to stop this conversation, I’m creeping myself out! LOL
There used to be an Internet radio station that played music that had been used in adult movies, and while most, of course, was pure dreck, some was actually quite good.
Piero Umiliani (best known for Sesame Street’s Mah Nà Mah Nà), Ennio Morricone (spaghetti westerns) and Riz Ortolani, were a big part of European 1960s and 1970s jazz influenced film soundtracks, and their music was very inexpensive by US standards.
The same with a lot of Space Age and Bachelor Pad Pop, like Henry Mancini, Burt Bacharach, Ferrante & Teicher, Mexico’s Juan García Esquivel (just known as Esquivel!), etc.
