I don't currently work out but used to and had a high-energy fast-paced random list of music I liked. When I say random, it was really random like Metallica to Daft Punk to Animaniacs to Broadway songs. One day, before earbuds were a thing, I happened to be recklessly flailing my arms on while on the treadmill and pulled my headphones cord out of the phone. Phone hit the floor blaring the song "Uncle fucker" from the Southpark movie. I scrambled to get to the phone and make my embarrassment less prolonged. Luckily, I think most other folks in the area were either too focused on their own activities or listening to their own music. Needless to say, from that day on, I was more selective in editing my playlists for various activities.
