for me the sound of the bike is the music. i want hear the motor and my shifts. i want hear as much as i can of everything that is going on around me. if a car rolls up beside me, i want to hear it. i can always listen to music in my office or at home.
I agree and it is one reason I enjoy my earbuds because the sound is better when worn under a helmet.
I do though enjoy the silence of the open road for just let your thoughts flow and find the craving sometimes to bring music is the avoidance of my own thoughts.
