I love Van HalenI don't mind it but if I was having a house party I wouldn't expect others to listen to it.
If I saw someone out on the trail listening to music I'd laugh out loud/wouldn't be able to help myself. It'd look 'odd'.
On the road? Maybe not as bad but then theres the car approaching from behind noise/closing off one of your most important senses.
Same with off road, listening/hearing helps with concentration and balance..
