Another song I thought of is Sultans of Swing by Dire Straits. I was about 10 when this song came out, and for me it ranks with Louie Louie, because I could barely understand a word of it. It took me a while to figure out that it was about a band playing in a club somewhere, but I had no idea what else was said. What a Fool Believes by the Doobie Brothers was playing on the radio at the same time, and I've always had a soft spot for Michael McDonald because he's another vocalist who confused the crap out of me as a kid.
I could barely understand a word of that song as well.
I must work "fanatic eunuchs" into a sentence today.
