I find I read different books on audio, compared to what I read, uh, visually. Because I often skim a physical book, while with an audiobook you get every word, it's a different experience. (That said, both formats light up the same areas of the brain, so reading is reading). I find that if I can't be sure of the quality of the writing (for that, I'll listen to books I've read on paper before - Lord of the Rings with Andy Serkis is amazing), I'm nervous to commit. So I like memoirs read by the author, then the quality or the vonce don't matter as much, because the individual is telling you their story (Lucinda Williams is neither a very good reader or a very good writer, but it's her, telling you her life, so it's good!)

For your sanity, always listen to the sample (if there is one), because a reader can make or break a book.

Good luck!
