This one's always a favorite of mine. I've spent a lot of time playing on Pandora or Grooveshark/Spotify making my playlists for my characters. Some make actual sense, but others... range pretty far
@Marek Starchaser - This character revolves around surviving in the darkest of places. And also enjoying life to a pretty full form, when the time comes for it. His playlist revolves around darker sounds. Rob Zombie, Nine Inch Nails, Marilyn Manson with some Glitch Mob and DJ Shadow thrown in with occasional Beenie Man, Damian Marley. Theme song tends to be, when I need something to spark his muse, either Clubbed to Death or Closer by NIN
@[member="Jared Starchaser"] - This playlist is pretty similar. He's a very tech involved character, Imperial Knight, and fighter pilot within the Fel. Focusing around Daft Punk, Glitch Mob, Celldweller, with a spin of Powerman 5000 and Manson. Theme song is definitely Bear McCreary's version of "All Along the Watchtower" that has the Cylon intro, from BSG.
@[member="Token Waters"] - She's a bit of an odd ball. Character is a bit... cheery? Even if there is darkness in her past and her future. Her list has a pretty decent range. She'll muse well to Luke Bryan, Jason Aldean, Carrie Underwood, straight through to Don Omar, Shakira and out again to Sting and to Story of the Year. Themes that always get her muse rolling is "Desert Rose" by Sting and the version of "Rabiosa" with Shakira/Pitbull
@[member="Peyton Steele"] - Maybe my oddest personality-to-playlist mix. She ranges from Flo Rida to Krewella to Rob Zombie to ZZ Top. She's a gun for hire that will take the jobs she wants (typically with darker bosses), so its strange that "Wild Ones" From Flo Rida is a theme for hers, the other is the back beats from "Velcro Fly" by ZZ Top, but she's a gunslinger, a la the Dark Tower, for her original shaping of muse. So its a throw back.
