When you are happy, loud music does not bother you; you would be immersed in it like everyone else there, feeling part of the group, bathing in the same foam, not just watching people and getting annoyed by them like grouchy old people sometimes; just like Smoke would not annoy you when you are smoking. Similarly, in a health club, loud exercise music would only excite you to do more and faster exercise when in sync with the instructor’ steps; all those scenes would aggravate you when you are off season.
