MP3 Player or not, in my opinion it just comes down to consideration. If you're on the course at 7am, no one wants to hear it that early! If you're with a course full of people, keep it to a minimum, just common courtesy. If you've got the course to yourself, bust it out, don't blast it to offend nearby neighbors though. I have one, but so do others in our group, I will hear it if it offends anyone and I have no problem turning it off, I'm out there to throw and have a good time, so who am I to ruin someone else's time? Use your common sense and think of others.
