Thank you areivimzehlazeh.
On a personal note… I feel that non jewish music as a rule has a negetive affect on a person i have seen it on many occasions, one of the first things that a boy/girl does on their way to leaving the derech is listen to non jewish music thats a fact that i have noticed whilst dealing with these types of boys.
The reason i believe is not so much the actual music but the lyrics, they are so trashy its astounding!!! i mean have you ever listened to what they sing about?!? not only that the people singing them arent exactly the type of role modles youd like your kids to follow, it starts with listening to this type of music, then following the carrer of the artist, going to concerts, meeting people i would be seen dead with!! etc etc etc one thing leads to the next!!
As for beethhoven all you have to do is listen to the difference in style……….
