"[8] Conversely, Interrante said that it "doesn’t seem to lyrically parallel Brian Wilson’s personal life at the time ...

"[9] Biographer Jon Stebbins praised "Kiss Me, Baby" as "the pinnacle of balladry", one of the group's "most romantic and emotional songs", and "a mammoth artistic achievement".
