DOES MUSIC SOOTH POLES' MORES?

In Polish there is a saying "Muzyka łagodzi obyczaje" (music soothes/softens mores). In English it is said that "Music sooths the savage beast". But in Poland after leaving discos young people have been known to demolish cemeteries and engage in other vandalism, stab fellow-revellers and engage in other such highly unsoothing activity. You rarely see this amongst those leaving the philharmonic, a Mazowsze concert or church, where music is also played.

The question arises which of the following alternatives is true: is the saying alleging that music sooths mores false, or is rap-crap, rock-shlock, techno-crud, disco-porno and heavy muddle NOT REALLY MUSIC?

Last year i got talked into going to a techno disco in a local village....my god , after half an hour of that rubbish i wanted to hit somebody and destroy the town....
