Yeah, i dont get the loud music thing. I understand the "Loud pipes save lives" arguement.. i am on the fence with it, but that is me. The music blaring is just rude, especially since there are new many new bluetooth helmet options for listening that are not being inflicted on others. I does solidify the bias against cruiser bikes (HD).
Disclaimer: Yes, I was a loud 70s` music lover and inflicted my music on the world. I was a teenager, and as such, i had no regard for anyone else. Now I still listen to the same music (Physical Graffitti )when i ride my bicycle or the walking machine, but i have ear buds so my wife doesnt laugh at me.
