Apparently too much gamification can be a bad thing, as we'll become immune to it. But on a small scale can be an effective tool.
My experience has not been that the music has been incredibly loud, it's been quite pleasant in fact.
I found it quite funny when I first heard they were doing this at my local bus stop, I didn't think it would be a deterrent as it wouldn't have dettered me (I was a teen when they started doing this). Was surprised it worked though.
Britains main problem isthe criminalising of its youth. They steadily reduced the amount of money going to youth programs and centres, thereby reducing the amount of places and free activities that children could go to and do. So as a result more and more of them started hanging around streets and at malls as they had no where else to go. This scared people seeing large "gangs of youth and about, assuming they must be upto no good.
They are asked to move on by police or people because they are scaring people just by being there, made to feel like criminals and then we expect them to act better.
Britain has seen a drop in most criminal activity despite Labours addition of several thousand new criminal laws since they came to power in 1997. Yet most people think the country has got worse, and seem to blame the youth more and more.
