This BPM law is a complete joke, though, through and through. It won't actually accomplish what they (supposedly) want, and will just cause trouble for people.
And to be completely fair, my own country is/was dumb too: in the 1920s many places in the US tried to ban jazz music, and I believe they used tempo as part of the regulations. I don't know if there were ever any laws around it, but rock'n'roll also experienced backlash from establishment types.
