My experience is the opposite. People blast music or other sounds on flights all the time. In Europe it's also very common to smoke in public, including beaches, restaurants, areas around building entrances. Literring is also very common.

Even Switzerland is dirty because cigarette buts are everywhere. It's just that some % of the population are inconsiderate assholes and only heavy enforcement works vs than. Unfortunately this is something our current society is not willing to do.
