The first Beach Boys song I considered for this list of favorite “happy” songs was ‘God Only Knows.’ It’s probably my favorite of theirs. But I quickly realized that it’s pretty melancholy as love songs go.
So I went with my backup, another favorite of mine, ‘Wouldn’t It Be Nice?’ You could argue that this song is bittersweet as well — after all, it’s about a couple that can’t be together the way they want to be — but it’s musically exuberant.
