Sometimes my answer is "audiobooks are an acquired taste." I've been listening to them for maybe 20 years and I didn't like them at first but now I'm so addicted. I'm not patient enough to flop out on the couch and read many books, but I can run for two hours or bike for four and be completely immersed in an audio book. I've become anti-social in my workouts because I love my books so much.
Sometimes I steal Jeff Bezos's answer: "you don't choose your passions, your passions choose you." I happen to love books about business & entrepreneurship, I always have, and technology. I can listen for hours without a moment of boredom if it's a good book or podcast, and this is becoming the age of podcasts. So many great ones coming online. Much more interesting than listening to AC/DC again, awesome as that is.
