Anyone, repeat anyone, who plays their music so loud that others can hear it - whether those others are camped 100' away or fishing 500' downstream - and who objects when others complain, is at that moment a selfish, ignorant neanderthal who's completely dishonoring and disrespecting the natural solitude and quietude of the woods, and in so doing, disrespecting those who came to the woods to enjoy that solitude and quietude.

The solitude and quietness of the woods is the natural state of the woods.  Anything that intrudes on that natural state is just that; an intrusion, and an unwelcome one at that.  Passing boats, snow machines, aircraft, are all temporary intrusions.  The person who drops anchor or sets camp up and then blasts their tunes is the one causing trouble.  In Jack London's day men would settle such offensive intrusions on their solitude the old fashioned way.  That won't work today, and so the one desiring quietude is now victimized by the inconsiderate neanderthal.
