I would love to have the music, I think it would help me. But I am with those who say it is a safety issue. Certainly never do it on a multi-use trail. I can't think of how many times I approach a jogger who has earphones and they can't hear me when I say that I am passing. Frustrating and dangerous for both of us.

I know some people use them on the open road but I feel like I really have to hear what might be coming up behind me. I often don't catch them in my mirror.
