i like my music loud and fierce, i just don't play it when my card is throwing out of courtesy. many times i pull up on the lot, or get pulled over by a cop, and i am asked to turn it off, not down, and i comply out of courtesy. yes, even at league, people play what they want, and some golfers even wear earbuds so as not to distract or be distracted. some even take mulligans and practice shots, it's cool as long as i'm not on the pad or trying to putt. unless the song is "hold on" by wilson-phillips, then rock on!
