"Don't Talk (Put Your Head on My Shoulder)" is one of four songs on Pet Sounds where Brian is the only Beach Boy performing. Like the majority of songs on Pet Sounds, "Don't Talk (Put Your Head on My Shoulder)" is about a melodic and introspective view on desperation and a crumbling romance.
On the line "Listen to my heart...beat", Brian stated "I felt very deeply about that line. One of the sweetest songs I ever sang. I have to say I'm proud of it. The innocence of youth in my voice, of being young and childlike. I think that's what people liked."
Elvis Costello has been quoted as saying, "Last summer, I heard 'Don't Talk (Put Your Head on My Shoulder)' played on the cello. It sounded beautiful and sad, just as it does on Pet Sounds. So now you know, if all the record players in the world get broken tomorrow, these songs could be heard a hundred years from now."
