I usually use music to make me get in the feeling of a chapter. I wrote a story called Playgirl which was to Ladytron's song (Which is really essential to the story, if you listen to the Zombie Nation remix. . . Though I don't force my readers into certain music.). of course since it turned out to have more chapters the mood changes, so I had to find other songs, while some of them are more apparent than others, sometimes I get cool names. Through if I use a song title, I sometimes switch it up or add another word so it's not a direct rip off. Nothing I have posted though.
A long time ago, I took song fic to an entirely new level and wrote a story based on an album, each chapter having to match up with a song from one album, and still convey the story. It was difficult, but i really liked the idea and would love to do it again.
I have a pet peeve for really normal one word titles ex. 'Love' (I shouldn't complain I have a story called Blue). Sometimes it's the only thing that fits. But I'd rather have a 'And. . .' or really random word, that I have to open the dictionary for. If it's going to be one word I want it to pop out.
