This will be a huge problem for people on the ground reporting on news events like protests/riots. Often, people in the crowd are using portable bluetooth speakers and playing commercial music. There are FB accounts (and youtube, twitch, etc) that have several thousand people watching these protests/riots every night, and often make it to mainstream news outlets.

There should be a fair use exemption for live newsworthy events where the music isn't the focus. The music is just in the background and not the main point or even a secondary point. It's inconsequential and you can't even hear it clearly.
