Authors—the good ones, anyway—breathe life into their characters so they become three-dimensional beings who we see when we close our eyes and hear when we flip through the pages: real people who have mood swings, who overspend on things they want but don't necessarily need. They watch too much TV. On good days, they finally get six hours of sleep. They listen to music as a means of coping with or intensifying feelings. This is key. Everyone's life deserves a soundtrack. And so we chose 10 iconic fictional characters and gave them just that, while supplying you with accompanying Spotify playlists. Because you know Holden Caulfield isn't going around listening to light jazz on his iPod these days.
