This is technically is a list. These are the songs I think of when I read the Artemis Fowl books. Character by character, book by book.
Artemis Fowl II: This Ain't a Scene; It's an Arms Race by Fall Out Boy. Especially in the first and second books, but throughout the whole series. Also Unwell by Matchbox 20 in book seven
Holly Short: Decode by Paramore. Second book and on. Do It Like a Dude by Jessie J throughout the whole series.
Foaly: Paranoid by the Jonas Brothers. The whole series.
Commander Root: Another One Bites the Dust by either Queen or Glee cast; take your pick. For obvious and tear-jerking reasons, this is only from one to four.
Artemis Fowl I: Anything Like Me by Brad Paisley. Obviously just the concept and not the exact lyrics. Books two through seven so far.
Angeline Fowl: Army Of Love by Kerli. Because she's gonna take over the world with an army of love. . Books 2+ (I hope eight. That be totally weird if just randomly changed Arty's mom.)
Mulch Diggums: Do You Like Waffles by Parry Gripp. Because he likes waffles. And all other food. A lot. Whole series.
Opal Koiboi: I Feel Pretty by Julie Andrews. While she has the narcissism issue.
Trouble Kelp: Girl All the Bad Guys Want by Bowl For Soup. Whole Series.
Butler: Butler can share with Commander Root. They are, after all, kindred spirits.
Juliet: Beat It by Michael Jackson. All throughout. And Just A Girl by No Doubt.
