I analyzed the lyrical content of all the singles The Beach Boys released in the 60's (about 60 songs) and sorted them into categories of Surfing, Cars, Relationships, Christmas, Instrumental, and Other. Here's a pie chart showing what that amounted to.
But then for comparison's sake, I turned the car and surfing songs into one color on the chart and turned the rest into another color. This is what I got from that:
"Wax on, wax off..."
"But Mr. Miyagi, I don't see how this is helping me do Karate..."
"Pubic hair is weakness, Daniel-san!"
