My music comes from under me. There is one speaker on the right side of the bike, aimed aft.
Part of being on the bike is the lack of car/truck features, radio included.
Also, listening to the vehicles around me clues me into where they are if they're flanking me in my blind spot and if they're accelerating or decelerating.
