I always have a disc playing in the car (it's the best music system I have at the moment and doesn't require a headset). I usually get story ideas from music when I'm driving to or from my mom's which is 1 to 1-1/2 hours away depending on the traffic, how many lights I hit red and whether the UP is running freight at a few crossings. I usually do the oldies (you've seen some of the results here) or movie/show music. I find that some songs/artists work in more than one fandom. I'm playing with recycling the chorus to Bruce Springsteen's Atlantic City to a Sherlock fic because I need the same "not dead" vibe I needed for an Enterprise profic drabble. On the other hand, rewriting part of Born in the USA (Born in the Queen's UK) for the same fic will be a little different.
I can't listen to music and write, either. Transcribe, yes (as long as I can hear the dictator), but come up with my own work, no. Can't do serious math (like taxes) with music, either. Would be interesting to do a color-coded CAT scan to see what parts of the brain light up when doing those things.
