i'd think self-hosting or smaller platforms might be able to circumvent this... I've may have asked before but... Why aren't the cops hit with license violations for public performance of these songs? They likely don't have a BMI license (or... whatever you need).
Because when you're in a position of power you get to do what you want. But probably also that playing on a personal device is not considered public performance (although courts have ruled officer actions on duty are public and recording them is not subject to privacy most laws, which could make it public performance, but good luck getting a court to agree)
