I like the last question. Answer the latter question with regulative scripture. What legal statement in scripture declares specific forms of music to be "unfruitful works of darkness?"You are asking the wrong question. The right question is, Are some kinds of music "unfruitful works of darkness"?
I will keep pushing you to show the clear regulations that explicitly make your point.
The answer to that is that you have none. You are making vague implications from verses that you imagine make a point for you, but you have none.
Since there is no explicit law on this subject, we are therefore left to our conscience. This means Romans 14 is our guide. I leave you to your conscience and if we ever met, I would not attempt to shake your conscience. This is grace and I would extend it to you.
