The Golden Rule of novel revision for music nerds who have just discovered buried musical treasure is this:
Never, never, never, never, never succumb to the temptation to Google song lyrics, paste them into iTunes' Info > Lyrics feature, and then read them the next three times you listen to the song so you learn them.
Not only does this halt all eating, Facebooking, and similar novel-revision-related tasks while you are learning the lyrics; this dramatically slows down all future productivity once you have them memorised and want to sing them while writing about deadly plagues and Y2K-like computer viruses. This is very difficult when you are listening to a rock song with an odd lyrical rhythm that demands your complete concentration to get the timing right.
Heed this advice and your novel is far more likely to survive the harsh uncharted territory of revision.
