Agree - numberous people have called the police. I’ve also called the city as it seems to be coming from the Municipal works.
Can someone please investigate.

I have seen a blue Honda CRV, with music boxes on top, playing music right below the turn, underpass from Bayonne to 440, the underpass that vehicle was there playing the music. There is a shop next to Sandy's auto body, a music install shop. The vehicle is always there with the speakers covered up in black. That's where you should start.
