singing or playing heavy downbeat music which is what most rock music is in the age. It is a sign of the end of a civilization according to Confucius, the other sign being the tattooing and marking of the body being popular. Heavy downbeat music has a negative effect on the nervous system and should be banned. Classical music and hymns to HaShem are to be preferred. Even martial music does not have a negative effect on the nervous system, but heavy metal downbeat music is very toxic and satanic and should be shunned. How stupid people are to buy or listen to such garbage.
