Though I liked the song better before seeing the cheesy music video, "Ahab" by MC Lars is a great example of how this initially daunting text is still interesting enough to write a silly song about. Nerdcore rap, no less.
Look for his references to hubris, Oedipus, and the importance of Ahab's scar. Anyone else find interesting pop-culture references to Moby Dick? Link to them in your comments!
