By now, playing music and videos aloud in public is widely considered to be a cardinal social sin in the era of ubiquitous headphones. Still, there is a certain segment of the population who seem to take pleasure in inflicting their portable speakers on the world. Every day, whether on the subway in the city or at a park in the suburbs, one of these people will materialize with a grenade-size device carabinered to their hip, playing a mash-up of the most annoying Top 40 hits from the past 20 years, or watching a TikTok video backgrounded by the same song sped up, before quickly scrolling to another video narrated by a blaring robo-voice.
