Also in parks please (at least in the US). I’ve noticed an increasing trend of mostly young people blasting their unwanted music through loud speakers at peaceful parks, ruining the experience for everyone else.

Living in a place where a lot of people does this, I'm all for it. Even more, ban people doing their "walkie-talkie" conversations on Whatsapp in loud voice.

I am all for total ban of loud music. If it leaves your car, office, place of work or home it should be prosecuted.

You're on public transit, it's inherently a noisy place. We all know what this is really intended to accomplish.

This would lead to extremely racist-looking enforcement, and therefore even if passed it won't be enforced.
