Nick & Norah's Infinite Playlist

The city feels alive and integral to the story, almost like another protagonist. Was this a conscious choice to reflect the characters' moods or growth?

The music feels so thoughtfully woven in — I wonder if the author chose songs based on personal favorites or to evoke specific emotions in readers.

This limited timeframe creates a sense of immediacy, but I’m curious if it was always planned or emerged during the writing process.
