Who is Frogman? There are many Frogmen inside "The" Frogman, all stored in the recesses of his mind. When the music is resonant to some memorable experience, it will excite that memory.
Frogman doesn't make a concentrated effort to hear the music, he lets it come to him. That's when it will excite the emotion associated with the memory of some long forgotten event. That's what listening cerebrally is about.
Right now "Last Tango in Paris" is on my rig, it's the lush one associated with the movie. I see Marlon Brando and his lady without a name doing the Tango in Paris. This music excites all the memories I can associate with that movie. I made no conscious effort what so ever for this to happen, the music excited the memory it was resonant to; that's what listening cerebrally is about, it's letting your psyche do the listening.
I'll respond if this needs clarification.
Enjoy the music.
