What is the name of my dream job?

I'm getting an audio engineering degree this spring and have narrowed down what precisely I'd like to do with it.

I have a sixth sense about finding what scenes in movies/ tv shows / etc match with what song. Conversely if you play me a song I can write out an entire scene in which would encapsulate the essence of said song.

However, I just don't know what the person who does that job for films/tv is called or what their title would be. Until I know that there's not much I can do but poke around and ask other people.

If anyone has ideas or the description of said job title I would love to know. Thanks.
