I know this isn't what you want to hear, but why not try running without any music?? Get off road as much as possible (much better for the knees) and listen to the world around you. If you are concentrating on your music, you greatly increase your chances of getting run over, and if you are not concentrating on the music, what's the point of it? I've been a runner for 35 years and never take my iPod on a run, but I have running friends who have horrific near miss stories due to listening to music.
