I can tell you are new to where the internet stands with Ghostbusters Aster Phoenix, on the internet it's kind of accepted that when you want to refer to that theme song you do not sing it and you do not mention it by name. You simply call it "that" theme song - see ^_^zexion's real wife^_^'s post for a perfect demonstration.
Yeah, see, but internet acceptance is kind of gay anyways. If there's something strange in your neighborhood, who you gonna call?~
