Oh, there are lots and lots! When I’m working on a story, I seem to find a way to relate any song I hear to a character. Some of my top picks:
Changing by The Airborne Toxic Event for Linden (I first heard this song while drafting the third book. Do with that what you will).
If You Could Read my Mind by Gordon Lightfoot for Gabriel. Laugh if you want, it’s okay, I won’t feel bad. Also for him, Violet Hill by Coldplay.
To the Moon and Back by Savage Garden for Cecily.
Paradise by Coldplay for Jenna.
When I Ruled the World by Coldplay for Vaughn. Also Zombie by The Cranberries. My reasons are probably obvious by the lyrics.
Ruby Tuesday by The Rolling Stones for Rhine.
In the Aeroplane Over the Sea by Neutral Milk Hotel and 24 by Jem for… everyone, basically.
