I prefer to listen to music when I run, although I don't have a specific genre as I am a "mood listener." I have listened to everything from Christian to country to jazz to rock.  Whatever I am feeling at that time is what motivates me and helps me maintain a pace. Running for me is an escape so podcasts don't work as well. And when I run trails I don't like to have headphones in, both for safety and to be able to enjoy the quiet sounds of everything around me.  Very relaxing!
