Within two months, Capitol assembled the group's first greatest hits compilation, "Best of the Beach Boys", which was quickly certified gold by the RIAA. Capitol A&R director Karl Engemann theorized that because the marketing department "didn't believe that "Pet Sounds" was going to do that well, they were probably looking for some additional volume in that quarter." There were reports that when record shops ordered copies of "Pet Sounds", they instead received "Best Of". On July 18, "Wouldn't It Be Nice" (B-side "God Only Knows") was released as a single, peaking at number 8 on September 2. "Billboard" ultimately ranked the album at number 43 on its "Top Pop Albums of 1966" list.
