DaasYochid,
Doesn’t make a difference who actually wrote the song any more then it makes a difference if a “Rap” song was written by a Jewish person. In fact what we are talking about certain style songs written by Jews, and if that is/should be a problem.
The things you base it on are all subjective. The same music and neshama “experts” who today say that Rap and rock music is “Vulgar” said the same thing about Jazz (and anything other then classical music for that matter) in the early 1900s.
