I can appreciate an app like Focus@Will that supposedly streams music to your ears from a genre that helps you be more productive. And I’m sure it’s effective for some subset of the population. Except… have you seen my playlist? It crosses so many genres and styles that most people who see it have the unfortunate experience of having their brains boil out their ears. My playlist is perfectly suited to my own productivity, thank you very much. I don’t need any app to help me with that.
