Seems Paul spoke by the Spirit on another sticky area that was not quite black and white...
"1Now about food sacrificed to idols: We know that “We all possess knowledge.” But knowledge puffs up while love builds up.
2Those who think they know something do not yet know as they ought to know.
3But whoever loves God is known by God.

4So then, about eating food sacrificed to idols: We know that “An idol is nothing at all in the world” and that “There is no God but one.”
5For even if there are so-called gods, whether in heaven or on earth (as indeed there are many “gods” and many “lords”),
6yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live.
7But not everyone possesses this knowledge. Some people are still so accustomed to idols that when they eat sacrificial food they think of it as having been sacrificed to a god, and since their conscience is weak, it is defiled.
8But food does not bring us near to God; we are no worse if we do not eat, and no better if we do.
9Be careful, however, that the exercise of your rights does not become a stumbling block to the weak.
10For if someone with a weak conscience sees you, with all your knowledge, eating in an idol’s temple, won’t that person be emboldened to eat what is sacrificed to idols?
11So this weak brother or sister, for whom Christ died, is destroyed by your knowledge.
12When you sin against them in this way and wound their weak conscience, you sin against Christ.
13Therefore, if what I eat causes my brother or sister to fall into sin, I will never eat meat again, so that I will not cause them to fall." 1 Corinthians 8:1-13.
If we take the precept from 1 Corinthians 8....Does it not depend on conscience and maturity? To some, it is fine and they do not grow distant from Christ. For others, it is a stumbling stone best avoided. And both are right for their own walk with Christ.

And as always, we are to do all things in love. A Christian who has the freedom to listen to secular music ought to be aware of those around him/her who may not share that freedom. A Christian ought not to condemn his brother or sister for listening to secular music either.
Let us do all things in love, with Christ as the motivation, and we will come out with the right answer/action every time.
