I've never really been a Beach Boys fan. Worse than hating them, I'm indifferent toward their music, except for one song. "God Only Knows".
I've always felt that song was possibly one of the best love songs ever written. It's simple declaration that without the one you love, your fate would be up in the air, is so concise, so brilliantly sublime. And then there's the symphonic music that adds a level of emotion. At 2 minutes and 24 seconds it is pure pop confection.
Not to mention the visuals are stunning.
