Was re-reading "Enchantment" by Orson Scott Card on the plane back to California today, and he did the SAME DAMN THING. In the middle of an otherwise excellent book, he makes his protagonist listen to this obscure album that Mr. Card was apparently rocking out to while writing the book. It's really jarring and obnoxious, and comes off like an in-joke. You'd think professional authors would know better, ya know?
