Sounds good to me and it falls under Disturbing the Peace. Those systems are very intrusive and most persons do not realize how much so. A low frequency tone is near impossible to keep from hearing. Try this one the next time you hear the booming. Place your fingers in your ears tight. You will still hear it. Place your hands over your ears tight you will still hear it. Put on shooters muffs you will still hear it. Why? Because low frequencies penetrate the skull. The skull is part of the Vestibular or hearing system.
They have NO RIGHT for their music to invade my person. The music until out of hearing range is impossible to not hear. To those seeing this as racial white teenagers & early 20's are the worst offenders actually.
You're right about how bad this "music" is and how impossible it is to block low frequencies.
