Re: A genuine question.
The irksome cause of most people's ire was Section 63 (1) (b) and similar references to "music":
63 (1) (b) “music” includes sounds wholly or predominantly characterised by the emission of a succession of repetitive beats.
This in essence sought to criminalise rave/dance music, hence the law becoming charaterised as NRB (No Repetitive Beats).
The trespass and noise limitation aspects were perfectly acceptable to most people.
