In the 1990s, Brian credited Carl with the title. Carl said with uncertainty that the name might have come from Brian: "The idea he had was that everybody has these sounds that they love, and this was a collection of his 'pet sounds.' It was hard to think of a name for the album, because you sure couldn't call it "Shut Down Vol. 3"." Brian commented that the title was a "tribute" to Spector by matching his initials (PS). Wilson's (since-discredited) 1991 memoir "" writes that the title was inspired by Love asking "Who's gonna hear this shit? The ears of a dog?" Love disputed that claim.
