"Audiobook?"
The "background music" was so loud it overpowered the narrator. Who wants music in an audiobook, anyway? Either the producer/director/publisher of the audiobook didn't believe the narrator was good enough to carry it off (and I can't comment on that, since the narrator's track was inaudible above the din of mood music), or they believed the listener couldn't follow the plot without some assistance. Either way, this was a waste of a book credit. Sad, too, because Stine's writing is so enjoyable.
